I've used my Ubuntu 22.04 installation for around 6 months now for work (software development work). Yesterday morning all was fine as usual, but when I came back from lunch, the entire system was extremely slow.
- Launching applications takes minutes instead of ~1 second
- The system stops responding to input for ~10 seconds and then processes the input
Overall, the system is completely unusable for productive work. I tried:
- Updating all packages via
aptandsnap - Restarting several times
- Removing power from the machine entirely
- Monitoring system resources. RAM, CPU, network and disk are barely used at all (!)
- Only starting a single program
- I booted up Windows (on a separate hard drive), which is working perfectly fine and fast
- Ran a disk self-test on the SSD Ubuntu is installed on, it came back as "Disk is OK".
None of this worked. Since it's not a problem or running out of RAM or CPU power I'm quite unsure what could have caused it to become so slow after being very pleasantly fast for half a year.
My specs:
- CPU: i7-7700K (aging model but working well under Windows)
- 32 GB RAM
- RTX 3060 Ti Graphics Card
- Gigabyte Z270-HD3P Mainboard
Since my dual-boot Windows works very well I can narrow down the problem to the Linux Software or the SSD that Ubuntu is installed on.
And pointers are greatly appreciated!
