Hi guys! I’m a bit tired that my system sometimes completely becomes unresponsive while running things that could fill up the memory. I have 32GB of RAM, a bit of a swap file in my SSD (I think something like 5GB swap), but this clearly isn’t cutting it. I was having a few browser windows opened, a handbrake encoding that was paused and decided to open Death Stranding 2, which is optimized to take around 5-6GB of RAM. And the system became once more so unresponsive that I had to literally reset it, after 5mins of nothing. I’d like to implement in my Ubuntu-based distro what they have in CachyOS. I’m not exactly sure, but I think it’s a ZRAM-based swap partition? Something like 1 or 2GB commited to compressed virtual memory in RAM? Seems this works much better when things are close to getting dicey…how would I go about doing what they use in CachyOS? Is there any easy to follow guide?
When your system starts swapping it will also start to crawl. Just set up an oom protector, then when you run out of ram, the system will kill the culprit automatically and your system will never crawl, and you get a notification what’s happened and why.
