Just got a brand new install of Ubuntu 20.04 and it's running rather slow.
I was using 20.04 before and it was snappy, recently I had to get rid of that and start again.
I've got largely the same programs with the only notable exception being that I'm using Brave instead of Chrome.
- CPU : Intel® Core™ i5-4460 CPU @ 3.20GHz × 4
- GPU : GeForce GTX 960
- RAM : 16 gb
- Motherboard : ASUS H97-PLUS
My system is on an SSD, there is an old HDD in the PC but it's not even mounted. I'm using Nvidia's driver nvidia-driver-440.
Clicking on windows is regularly taking a second to respond. Things like the windows key take 3ish seconds to show up.
When looking at the CPU monitor I'm very low on usage. Currently they are all hovering around 10 - 20 % (I have 2 docker sites running and 2 IDEs atm, but it's slow even with them off).
The only difference from my previous install is Brave. Any thoughts as to what's up?
