Hey folks! I'm currently facing a major issue with my Windows Server 2022 setup. I'm hosting a backend service that isn't very demanding, yet whenever I trigger it, the server goes into overdrive with CPU usage spiking all the way to 100%. It's incredibly frustrating because the performance is sluggish and it often fails to process requests. My server specs are decent, with 16GB of RAM (which is enough since the backend only uses about half of that) and an 8-core CPU running at 2.49GHz. The real problem seems to stem from the 'System interrupts' process, which is taking up more than 70% of the CPU, making the server nearly unusable. I'm working with LightNode for hosting. Has anyone experienced similar issues on their Windows servers? Any suggestions or insights would be greatly appreciated! Thanks!

It sounds like you might be dealing with a VPS situation, which could mean that your virtual CPUs are struggling if the physical server is busy with other users. Check Resource Monitor to see if your disk is showing high active time or long queue lengths; that might help determine if it's a disk IO issue rather than CPU-related. It's worth investigating!
Why are people still using Windows servers for production? I've heard from many ops folks that they're not thrilled with how Windows handles server tasks, especially when compared to other options. Just some food for thought!
I've noticed similar spikes in performance on Windows Server 2022, though not quite as high as 70%. In some cases, just updating or rebooting the server temporarily alleviates the issue. Disabling Azure Arc in Server Manager seemed to help us a lot. Also, if you're using SQL Server, avoid the latest version—it has been notorious for slowing things down unnecessarily!
Totally agree! Microsoft's approach to Azure integration is causing some strange performance issues. It's frustrating, especially when these features aren't even being utilized.
I'm guessing there could be a hardware issue behind this. It might be worth running some diagnostics to see if there’s an underlying problem with the CPU or memory that’s causing the high usage.
Without diving deeper into your setup, it’s hard to pinpoint the exact cause. If you’re running a database, I’d suggest using Performance Monitor or Process Monitor to gather more detailed info about what’s causing the bottleneck. It could be anything from a misconfigured service to resource contention.
You're spot on! Microsoft has been making some odd decisions lately about their integrations, especially with SQL Server. It might be worth checking if global disk caching settings are impacting your performance. Some legacy settings are slowing things down for no good reason.
