How much RAM does a VPS need? A guide by use

For a simple website or bot, 2 to 4 GB of RAM is often enough. For a game server, Docker with several services or a database, you often need more. These figures are rough guides: the right amount comes from measuring your own usage over a few days.

• Measure RAM at peak usage before choosing the server size.
• A simple site often fits in 2 to 4 GB; Docker and databases need more.
• Keep about 20 to 30% of margin for the system and peaks.
• The Linux Mini plan gives 8 GB of RAM for 4.99 € as of 7 November 2026.

Measure what you already use

If your application already runs, measuring is more reliable than any table. Run free -h for overall memory, htop for the detail per process and docker stats for each container, at peak times.

• Record memory used at peak, not only at rest.
• Usage that keeps growing points to a leak: the problem is in the software, not in the server size.
• Watch swap: if it grows, RAM is short.

Guide values by use

These rough values apply to a standard installation, without mods or heavy traffic. Adjust them to what you measure.

• Static site or blog without a database: 2 GB is often enough.
• WordPress with its MySQL database: 4 GB to start, more with heavy plugins or traffic.
• Discord bot: often 1 to 2 GB, more with audio playback.
• Minecraft Java server: 2 to 4 GB for a small group in standard form, more with mods or many players.
• Docker with n8n and PostgreSQL: 8 to 16 GB depending on the number of services, see a 16 GB Linux VPS.

Keep a margin

Available RAM should never drop to zero: the system, the cache and peaks need room. Keep about 20 to 30% of margin above your peak usage. A server that uses swap slows down well before it is full.

• On a game server, the margin avoids stops during backups and world loading.
• Do not pay for capacity you will never use: measure first, then choose.

Why choose ACLClouds for your RAM

Linux plans come with a fixed amount of RAM, which keeps comparison simple. As of 7 November 2026, Mini gives 8 GB for 4.99 €, about 0.62 € per GB, and Pro gives 64 GB for 34.99 €, about 0.55 € per GB.

• Mini: 8 GB of RAM, 2 vCPU and 40 GB of storage, at 4.99 €.
• Essentiel: 16 GB of RAM, 4 vCPU and 80 GB of storage, at 9.99 €.
