How Much CPU, RAM, and Storage Does a VPS Need?

How Many Resources Does a VPS Need?

Choosing a VPS is not simply a matter of ordering the server with the most CPU cores or RAM. The required configuration depends on the software, number of users, website traffic, database size, and type of workload.

A small website or personal VPN may need only 2 CPU cores and 2GB of RAM. An online store, CRM system, large database, or Windows environment will require significantly more resources.

This guide explains how much CPU, RAM, and storage different workloads require and which ForceVPS product line is the most suitable.

What Determines VPS Requirements?

Before selecting a plan, determine:

• which operating system will be used;
• which applications will be installed;
• how many websites or services will run on the server;
• how many users will work simultaneously;
• how much traffic is expected;
• how large the database is;
• whether a control panel is required;
• whether Docker containers will be used;
• whether the application depends on single-core performance;
• how much space is needed for files, logs, and backups.

Two projects with similar traffic can use very different amounts of resources. The workload is affected by the CMS, plugins, database queries, caching, and software optimization.

What Is CPU in a VPS?

The CPU executes application code, processes requests, runs database operations, archives files, and handles system processes. VPS specifications usually list the number of virtual CPU cores, or vCPUs.

More cores allow the server to perform more tasks simultaneously. This is important for multiple websites, Docker containers, parallel requests, and multithreaded applications.

However, core count is not the only measure of performance. Some applications benefit more from higher frequency and faster single-core performance.

When the number of cores matters

• the server hosts many websites;
• many PHP processes run simultaneously;
• Docker containers are used;
• background jobs and queues are active;
• the application supports multithreading;
• the server handles many concurrent requests.

When high CPU frequency matters

• a game server primarily uses one core;
• a trading terminal is running;
• the application creates a single-threaded workload;
• complex database queries are executed;
• the application cannot efficiently use multiple cores;
• minimal processing latency is important.

For these workloads, a VPS with fewer but faster cores may perform better than a server with more cores running at a lower frequency.

How Many CPU Cores Are Needed?

2 cores

Suitable for a small website, landing page, personal VPN, Telegram bot, test environment, small API, or a single WordPress website with moderate traffic.

4 cores

Suitable for several small websites, WordPress with many plugins, a small online store, a CRM system for a small team, several Docker containers, or a Windows VPS running basic applications.

6–8 cores

Suitable for a large online store, multiple production websites, CRM or ERP software, a database under sustained load, a high-traffic API, a game server, or a Windows environment with several users.

12 cores

Suitable for large databases, resource-intensive business systems, many websites, intensive parallel processing, large Docker environments, and applications with sustained heavy workloads.

If an application uses only one or two cores, upgrading from 8 to 12 cores may not noticeably improve its speed. A high-frequency VPS may be a better choice.

What Is RAM in a VPS?

RAM is used by the operating system, web server, database, cache, PHP processes, control panel, and other applications.

When RAM runs out, Linux may begin using swap, which uses disk space as slower memory. If memory is critically low, the system may terminate running processes.

Insufficient RAM can cause:

• slow website performance;
• 502 Bad Gateway errors;
• MySQL or MariaDB shutdowns;
• terminated PHP processes;
• an unresponsive control panel;
• poor Windows Server performance.

How Much RAM Is Needed?

2GB RAM

A minimum configuration for a small Linux server, personal VPN, simple website, Telegram bot, or test project. It may not be sufficient for a full control panel, large database, or multiple websites.

4GB RAM

Suitable for WordPress, several small websites, a lightweight web application, a basic Docker environment, a small CRM system, or a server with a lightweight control panel.

8GB RAM

Suitable for an online store, WooCommerce, OpenCart, several production websites, a small-team CRM system, multiple Docker containers, an entry-level Windows VPS, or a medium-sized database.

12–16GB RAM

Suitable for a large online store, CRM or ERP system, large database, several resource-intensive websites, a multi-user Windows environment, or many Docker containers.

24–48GB RAM

Suitable for large business systems, Windows Server with multiple active users, large databases, demanding CRM and ERP systems, many websites, and applications with sustained heavy workloads.

RAM Requirements for Linux and Windows

Linux without a graphical desktop generally uses less RAM. A small Linux VPS can operate with 2GB of RAM if it does not run a demanding control panel or large database.

Windows Server requires more resources for the operating system, graphical interface, services, and RDP sessions. An entry-level Windows VPS should have at least 8GB of RAM.

If several users will work simultaneously or run BAS, CRM, browsers, and office software, consider 16GB of RAM or more.

Control Panel Resource Usage

A control panel simplifies the management of websites, databases, mailboxes, and SSL certificates, but it also consumes CPU, RAM, and storage.

A panel may run a web server, PHP-FPM, database, mail and DNS servers, antivirus, spam filtering, backups, and statistics services.

Allow at least 1–2GB of additional RAM beyond the resources needed by the website itself. A panel running mail, antivirus, and multiple websites may require more.

Which Storage Type Should You Choose?

SSD

SSD storage is suitable for small websites, VPN services, test servers, file storage, and projects with moderate storage activity.

A standard SSD is a good choice when affordable pricing and storage capacity are more important than maximum database performance.

NVMe

NVMe provides higher speed and lower read and write latency. It is recommended for:

• MySQL, MariaDB, and PostgreSQL;
• high-traffic WordPress websites;
• WooCommerce and OpenCart;
• CRM and ERP systems;
• large product catalogs;
• Docker containers;
• frequent data imports and exports;
• high-load web applications.

NVMe is generally a better choice than standard SSD storage for databases and online stores.

How Much Storage Is Needed?

40GB

Suitable for the operating system, a small website, VPN, bot, or test environment.

80–120GB

Suitable for WordPress, several websites, a small online store, CRM system, or entry-level Windows VPS.

160–240GB

Suitable for a large online store, several production projects, a database, mailboxes, or a Docker environment.

300–700GB

Suitable for large Windows environments, file storage, large databases, game servers, and data-intensive projects.

What Uses Disk Space?

When calculating storage requirements, consider:

• the operating system;
• website files;
• databases;
• mail;
• system logs;
• cache;
• Docker images and containers;
• temporary files;
• software updates;
• local backups.

Do not fill the disk completely. Keep at least 15–20% of the storage capacity available for stable operation.

Backups stored on the same VPS can quickly consume all available space. Important backups should also be stored on another server or in external storage.

VPS for a Small Website

For a landing page, business website, blog, or small WordPress project, start with:

• 2 CPU cores;
• 2–4GB RAM;
• 40–80GB SSD;
• Linux.

An SSD VPS is suitable for these workloads. If the website frequently accesses a database or receives high traffic, choose an NVMe VPS.

VPS for Multiple Websites

For several small websites, consider:

• 4 CPU cores;
• 4–8GB RAM;
• 80–120GB storage;
• SSD or NVMe.

If the projects include an online store, CRM system, or high-traffic website, choose an NVMe VPS with at least 8GB of RAM.

VPS for WordPress

For a regular WordPress website with moderate traffic, consider:

• 2–4 CPU cores;
• 4GB RAM;
• 40–80GB SSD or NVMe.

If the site uses many plugins, a page builder, multiple languages, or extensive caching, 8GB of RAM is a better choice.

WordPress performance also depends on theme and plugin optimization, database configuration, PHP-FPM, and caching.

VPS for WooCommerce and OpenCart

An online store frequently accesses its database, catalog, search, filters, cart, and customer accounts.

A recommended starting configuration is:

• 4 CPU cores;
• 8GB RAM;
• at least 80GB NVMe;
• Linux.

For a large catalog, frequent product imports, or high traffic, consider 6–8 cores and 12–16GB of RAM.

NVMe VPS is a suitable starting point for most stores. A large store with sustained heavy load should use Force VPS.

VPS for a Database

MySQL, MariaDB, and PostgreSQL performance depends on storage speed, available RAM, and CPU performance.

For a medium-sized database, consider:

• 4–6 CPU cores;
• 8–16GB RAM;
• NVMe storage;
• additional storage for logs and backups.

More RAM allows the database server to keep more data in cache instead of accessing the disk repeatedly.

For a large database, complex SQL queries, and sustained load, choose Force VPS with a higher CPU frequency and NVMe PCIe 4.0 storage.

VPS for CRM and Business Systems

For a small CRM system, consider 4 CPU cores, 8GB RAM, and 80–120GB NVMe.

For a large CRM or ERP system, consider 6–8 cores, 12–24GB RAM, NVMe storage, and separate backups.

NVMe VPS is suitable for a small system. Force VPS is a better choice for a large database, complex reports, and many integrations.

VPS for BAS

If BAS runs on Windows and users connect through Remote Desktop, select a Windows VPS.

For a small number of users, start with 4 CPU cores, 8–16GB RAM, and 80–120GB NVMe.

For a large database and several concurrent users, consider 6–8 cores and 16–32GB RAM.

Also consider the database type, database size, background operations, and other applications running on the server.

VPS for VPN

A personal WireGuard or OpenVPN server usually requires:

• 2 CPU cores;
• 2GB RAM;
• 40GB SSD.

SSD VPS is suitable for a personal VPN. If many users connect simultaneously or transfer large amounts of data, consider the network port speed and included traffic.

VPS for Docker

For a small Docker environment, consider 4 CPU cores, 4–8GB RAM, and 80GB NVMe.

If a web application, database, Redis, search service, and monitoring system run simultaneously, choose 8 cores and at least 16GB RAM.

Docker images, logs, and unused volumes can quickly consume storage. Monitor and remove unused data regularly.

VPS for a Game Server

Game servers often depend on single-core performance. Both CPU frequency and the number of cores must be considered.

An NVMe VPS may be sufficient for a small test server. For a production server with many players, modifications, or active objects, choose a 5GHz VPS.

A typical configuration may include:

• 4–8 high-frequency CPU cores;
• 8–16GB RAM;
• at least 100GB NVMe;
• fast network connectivity.

VPS for Trading

Trading platforms require stability, fast single-core performance, and low network latency to the broker’s server.

If the software runs on Linux, consider a 5GHz VPS. If MetaTrader, another Windows terminal, or RDP is required, select a Windows VPS.

A high CPU frequency cannot compensate for high network latency, so consider the locations of both the VPS and trading platform.

• game server — 4–8 high-frequency cores, 8–16GB RAM, NVMe;
• Windows and BAS — at least 4 cores, 8–16GB RAM, and 80GB NVMe.

These are general estimates. Actual resource usage depends on the software, optimization, and workload.

How Much Spare Capacity Should You Keep?

For a production project, try to keep:

• 20–30% CPU capacity available during normal load;
• 20–30% RAM available;
• at least 15–20% free storage space;
• additional capacity for updates, backups, and traffic peaks.

When Should You Scale the VPS?

More resources may be required when:

• CPU usage remains close to 100% for long periods;
• the server regularly runs out of RAM;
• swap is used heavily;
• little free disk space remains;
• websites have become slower;
• 502 or 504 errors occur;
• database queries take too long;
• services stop responding during peak load.

Before upgrading, check the software configuration. The underlying cause may be an inefficient SQL query, an application error, missing caching, or a process consuming all available resources.

Conclusion

A small website or VPN usually needs 2 cores and 2–4GB RAM. WordPress, multiple websites, or a small CRM system are better served by 4 cores and 4–8GB RAM. Online stores, large databases, and business systems require at least 8–16GB RAM, fast NVMe storage, and more CPU cores.
