Why is Ubuntu slow?

Question

ubuntu

I installed ubuntu, it works very slowly, although I have not installed anything from third-party programs yet. launched firefox in general, it became buggy in a hard way

, version 14.04 used to be, but there were no such problems. Now 16.04
ps was also installed for a long time, almost an hour

Answer 1

Most likely the problem is in the video driver, the default is nouveau (if the card is from nvidia), try installing a proprietary driver. I had a similar problem, it worked.

Answer 2

Video card drivers installed?
Your compiz and firefox ate two cores for two. It is very strange...

Answer 3

If the processor is an old AMD, then its driver may be broken in newer cores. This is manifested in the fact that the processor frequency does not change depending on the load and is always set to the minimum. In general, you should try to look in /proc/cpuinfo.
You can also try to put the Low-Latency kernel instead of the standard one.

Answer 4

in 16.04 there were terrible memory leaks, the developers wrote about this after many complaints about freezes and the fact that the system EATS a huge amount of RAM. You can search the net for information about this. I myself could not work in either 16.04 or 16.10 or 17.04. There, in chrome, after opening 7-10 tabs, the system hung and stopped responding, I had to constantly restart the computer. I 'm generally silent about working with graphics .....
Now I'm writing from 17.10, there is nothing that was in previous releases, but if you work with graphics ...... The situation remains the same. I'm waiting for 18.04 where they promise to eliminate hundreds of BUGS related to the operation of the processor and improve performance in general :)
