The Best ARMA 3 Server Hosting

Hosting an ARMA 3 server

ARMA 3 servers are built for large-scale military simulation, and the workload is unusual: AI processing is the heavy part, and it leans on a single thread. Big missions with many AI units can slow a server sharply, which is why experienced communities offload AI to a separate process called a headless client.

What to compare

• CPU performance. Strong single-core speed matters most, and a plan with more cores can also help if you run headless clients.
• Headless client support. For AI-heavy missions, a headless client offloads AI work from the main server. If you plan to use it, check the host supports running one.
• Workshop mods and mod sets. Communities usually run large mod sets such as ACE, CBA and RHS. Check the host lets you install and manage many mods, and keep server and player mods matched.
• Mission and file access. Missions, server configuration and BattlEye settings are managed through files, so direct access or a solid panel is important.
• RAM and storage. Large modded servers use plenty of memory and disk space, so compare plans against your mod list.
• Restarts and updates. Mods update often, so a host that makes it easy to update and restart saves a lot of time.
• Location and DDoS protection. Organised operations depend on a stable connection, and public servers attract attacks.

ARMA 3 server hosting FAQ

What is a headless client?

It is an extra process that handles AI work so the main server can focus on players, which helps a lot on large AI-heavy missions.

Can I run ACE and RHS?

Yes, on hosts that support large Workshop mod sets. Server and players must run matching mods.

Why is single-core speed so important?

Much of ARMA 3's AI runs on a single thread, so a fast core keeps missions running smoothly.
