ubuntu 9.10 slow after hibernate or suspend

Asked by Aniruddh

I am running Ubuntu 9.10 on HPdv4 machine with 4 GB RAM and 5.2 GB swap space. After a resume from hibernate or suspend, UI becomes very slow, with words typed displaying after few moments. Even normal UI actions like changing tabs becomes slow. I was not sure what kind of information to collect for this problem. Any solutions or even suggestions for kind of data expected for this problem are welcome.

The slowness seems to be bursty and does not happen all the time. And when it happens, processor usage is not very high.

For example, when typing this message, the slow character display happened many times. I was running top in parallel and not once did I see any unusual usage. In fact when it happened, it was firefox which was running, taking up 57% of the cpu. So it is not clear why the display on firefox itself becomes slow when firefox is the task with highest cpu usage.

On further observation, I realized this is happening with firefox alone. Other programs seem to be running fine, including chrome. Since I use firefox most of the time compared to other programs, and since it worked fine before hibernate, I thought Ubuntu must have become slow. But most probably its a problem with firefox. Any suggestions about this problem? I am using firefox 3.6 but the same problem was seen in firefox 3.5 also which came with ubuntu by default.

Is there a way to change the summary of this question?

use chrome, firefox is garbage, maybe if you close firefox and then rerun it and see if its better

maybe its a known bug with (crappy) firefox

Can you help with this problem?
