Hey folks, I'm running my backend application on a Windows Server 2022, and I'm hitting a wall with CPU spikes that go up to 100%. It processes requests agonizingly slow and often fails due to the server being practically unusable, which is super frustrating! My server has decent specs — 16GB RAM, and the CPU has 8 cores at 2.49GHz. The RAM usage is fine, but I'm noticing that 'System interrupts' is hogging over 70% of the CPU, which seems way too high. Does anyone have experience with LightNode's Windows servers or know what might be causing this? Any help would be greatly appreciated! Thanks a lot!

Without more details, it’s hard to pinpoint the issue for sure. Are you running any databases? Try using the performance monitor to gather data on what’s causing the spike. Process Monitor can also help identify the culprit. It might give you some clearer insights.
I’d lean towards a possible hardware issue. If all else fails, you should definitely investigate that further. Sometimes, weird hardware quirks can really mess with performance, especially with VMs.
It sounds like if you're on a VPS with LightNode, you might be experiencing issues scheduling your vCPUs because the physical server could be overloaded with resources being shared among several customers. It's definitely worth checking Resource Monitor to see if your disk is maxed out on active time or disk queue length. You could be hitting high I/O wait times instead of your CPUs actually being busy.
