Why is your CPU spiking?
High CPU usage on Xtream UI is often caused by a bottleneck. Think of your CPU as a chef in a kitchen. If the orders (network packets) come in too fast and the kitchen (system configuration) is disorganized, the chef gets overwhelmed. We need to organize the kitchen so the chef can work faster.
1Step 1: The "Clean Up" Phase
Before optimizing the core, we need to remove dead weight that forces the CPU to work overtime.
- Check Process Monitor: Ensure
pid_monitoris running in your crons. It kills stuck processes that eat up CPU cycles. - Clean Streams Table: Go to "Stream Tools" in your panel and clean the
streams_systable. A bloated database forces the CPU to search through millions of useless records every second.
2Step 2: Increase Processing Limits (ulimit)
By default, Ubuntu limits how many tasks can run at once. Xtream UI needs to run thousands. We need to tell the server "It's okay to work harder."
Check your current limit:
If it is low (like 1024), edit the configuration file:
Add these lines to the bottom to unlock your server's potential:
Press CTRL+X, then Y, then Enter to save.
3Step 3: Optimize Kernel Traffic (sysctl)
This is the most effective fix for CPU spikes caused by network traffic. These settings help your server handle thousands of connections efficiently without interrupting the CPU for every single packet.
Open the system control file:
Paste these optimization settings at the end of the file:
Save and exit. Apply these changes instantly with:
4Step 4: Reboot and Test
Reboot your server to apply all changes. Once back online, check your dashboard. Your CPU usage should be significantly lower and more stable.
