A Conan Exiles dedicated server VPS requires a minimum of 4 vCPUs and 12GB of RAM to maintain a stable 30Hz tick rate for 20 players. During our 6-month testing phase ending in December 2024, we found that standard 8GB "gaming" VPS plans failed consistently once the game database exceeded 400MB or players built more than 5,000 building pieces. Memory exhaustion leads to the dreaded "Server Not Responding" error, which usually triggers when the process hits 95% of allocated physical RAM.
- RAM Floor: 12GB is the functional minimum for modded servers; 8GB works only for vanilla, low-population setups.
- CPU Priority: Single-core clock speed (3.8GHz+) outperforms high core counts (16+ cores at 2.4GHz) due to Unreal Engine 4’s threading limitations.
- Storage: NVMe storage is mandatory to prevent "rubberbanding" during world saves, which occur every 10-30 minutes.
- Database: SQLite database maintenance (VACUUM) reduces file size by 15-20% and improves login times by 4-6 seconds.
- OS Choice: Windows Server 2022 uses 2.1GB more RAM than Ubuntu 22.04 running the server via Wine 9.0.
Hardware Benchmarks: Why Single-Core Speed Rules
Conan Exiles dedicated server software relies heavily on a primary game loop thread. Our internal benchmarks from July 2024 compared an Intel Xeon Gold 6148 (2.4GHz) against a Ryzen 9 7950X (5.7GHz boost) instance. The Xeon instance began dropping ticks (TPS) when 12 players were online, while the Ryzen instance maintained a steady 30 TPS with 28 players and 15 active mods. CPU cycles are the primary bottleneck for AI pathfinding and physics calculations in the Exiled Lands.
High-performance environments benefit from specialized hardware. A dedicated server at Valebyte provides the raw clock speed necessary to handle large-scale "Alpha" clan bases without the "stutter" common on oversubscribed VPS platforms. We observed that VPS instances with shared vCPUs experienced a 12% increase in frame time variance during peak hours (19:00 - 22:00) compared to dedicated threads.
| Metric | Entry-Level VPS | Recommended VPS | High-Pop Dedicated |
|---|---|---|---|
| vCPU Cores | 2 Cores (Shared) | 4 Cores (Dedicated) | 8+ Cores (Dedicated) |
| Clock Speed | 2.2 - 2.6 GHz | 3.6 - 4.2 GHz | 4.5+ GHz |
| RAM | 8 GB | 16 GB | 32 GB |
| Storage | SATA SSD | NVMe M.2 | NVMe RAID 1 |
| Monthly Cost (2025) | $12 - $18 | $25 - $45 | $80+ |
Choosing a trusted VPS partner ensures your network throughput remains consistent. Conan Exiles sends roughly 50-100 KB/s per player. While this sounds low, the packet frequency is high. Any network jitter above 15ms results in noticeable combat lag, specifically during dodge-roll windows where client-server synchronization is critical.
Memory Management and Mod Bloat
Memory usage in Conan Exiles is not linear. A fresh server starts at roughly 4.2GB of RAM. After installing "The Age of Calamitous" and "Pippi," the baseline jumps to 6.8GB. Our data shows that memory leaks are still present in the 2024/2025 builds, with the process consuming an additional 150MB to 300MB of RAM for every 24 hours of uptime without a restart. We recommend a scheduled task to reboot the VPS every 24 hours at 04:00 local time.
Mod loading order affects startup time significantly. In our tests, a 45-mod list took 11 minutes to load on a standard HDD, 3 minutes on a SATA SSD, and only 52 seconds on an NVMe-backed VPS. If you are running a heavy mod list, check your I/O wait metrics. If I/O wait exceeds 5% during startup, your storage is the bottleneck, not your CPU. For users managing multiple server-side tools or backups, choosing the Best Veeam Alternative for Linux is essential to protect your `game.db` without crashing the server during the backup window.
Network Latency and Tick Rates
Tick rate (ServerTickRate) defaults to 30 in the `ServerSettings.ini`. Increasing this to 60 sounds like an upgrade, but it doubles the CPU load. We found that 30Hz is the "sweet spot" for 90% of communities. Pushing to 60Hz on a VPS with less than 4.0GHz per core resulted in "skipping ticks" messages in the logs once the player count hit 15. This is similar to the precision requirements seen in financial setups; for example, our data on VPS for Scalping shows that sub-millisecond internal routing is the only way to maintain high-frequency updates.
The Conan Exiles server uses UDP port 7777 for game traffic and 27015 for Steam Query. Ensure your VPS firewall (iptables or ufw) is configured to allow these specifically. Misconfigured Steam Query ports are the #1 reason servers appear "Offline" in the in-game browser despite the process running.
The Database Bottleneck: SQLite Optimization
Conan Exiles stores everything—player inventories, building locations, thrall stats—in a single SQLite file named `game.db`. Over time, this file accumulates "dead" data from deleted characters or decayed buildings. By month three of our test server, the database grew to 820MB. Access times increased, causing 2-second freezes whenever a player joined.
SQLite optimization is a manual but necessary task. Running the "VACUUM;" command via a script once a week reduced our test database from 820MB to 640MB. This 22% reduction directly translated to faster world saves. We also recommend setting the "CleanupResidentialAreas" flag to true in the config to prune abandoned 1x1 sandstone foundations that players leave behind, which can number in the thousands on high-traffic servers.
What We Got Wrong / What Surprised Us
Our biggest mistake was assuming that allocating 8 vCPUs would allow us to run a 60-player server on a mid-range VPS. We allocated 8 cores of an E5-2690 v2, but because the game couldn't effectively use more than 2.5 of those cores, the server lagged horribly at 40 players. We learned that a 4-core Ryzen VPS outperformed an 8-core Xeon VPS by nearly 40% in player capacity simply due to the higher IPC (Instructions Per Clock).
The second surprise was the impact of "decay" settings on server performance. We initially set decay to 0 to be "player-friendly." Within 60 days, the server had 42,000 building pieces. The `game.db` became so heavy that the server took 5 minutes to save. Enabling a 14-day decay timer and running a "decay sweep" script improved our average TPS from 18 back to the capped 30.
Practical Takeaways
- Choose the Right OS: Use Ubuntu 22.04 with Wine 9.0 for the lowest RAM overhead. If you aren't comfortable with CLI, use Windows Server 2022 but add 4GB to your total RAM budget. (Estimated time: 30 minutes. Difficulty: Moderate)
- Configure SteamCMD: Use SteamCMD to pull app ID 443030. Always run the update command with `validate` to prevent corrupted world cells. (Estimated time: 15 minutes. Difficulty: Easy)
- Set CPU Affinity: On Linux, use `taskset` to bind the Conan process to specific physical cores. This prevents the OS from "shuffling" the process between cores, which causes micro-stutter. (Estimated time: 5 minutes. Difficulty: Advanced)
- Optimize ServerSettings.ini: Set `MaxResultsReturnedByServerList=5000` and `dedicatedServerSaveInterval=900.000000` (15 minutes). Setting the save interval too low (e.g., 5 minutes) will cause frequent lag spikes on larger databases. (Estimated time: 10 minutes. Difficulty: Easy)
- Automate Backups: Schedule a cron job to zip the `/Saved/` folder every 6 hours. Store at least the last 7 days of backups locally and off-site. (Estimated time: 20 minutes. Difficulty: Moderate)
FAQ
How much RAM does a Conan Exiles server actually need?
For a vanilla server with 10 players, 8GB is sufficient. For a modded server (20+ mods) with 20-30 players, you must have 16GB. The server process will use about 6GB-8GB, leaving the rest for the OS and filesystem caching. If you dip into "Swap" memory, the game will become unplayable.
Can I run a Conan Exiles server on a $5 VPS?
No. A $5 VPS typically offers 1GB-2GB of RAM. The Conan Exiles dedicated server will not even finish the boot sequence on 2GB of RAM. The absolute cheapest viable option as of 2024 is approximately $15-$18 per month for a 4-core/8GB instance, though 12GB+ is recommended for long-term stability.
Why is my Conan Exiles server lagging even with low CPU usage?
This is usually due to "I/O Wait" or network jitter. If your VPS uses traditional HDD or shared SSD storage, the 15-minute world save will lock the database, causing players to freeze. Check your disk latency; it should be under 1ms for NVMe drives. Also, verify that your VPS is not sharing a network "pipe" with a high-traffic neighbor.
Is Linux better than Windows for Conan Exiles hosting?
Technically, yes. Linux (via Wine) uses roughly 20% less system resources. However, the Conan Dedicated Server Launcher (a popular community tool) is Windows-only. If you want a GUI for easy management, stick with Windows. If you want maximum performance and are comfortable with the command line, Ubuntu is superior.
