Jaunty 32bit abysmally slow since GTK+2.0 update

[JPorter]

Hello all!

I experienced a bug with lockup on boot following a GTK update last week, it was subsequently fixed with another GTK update, but since that time my system performance has been UNBELIEVABLY slow. Multitasking is a painful experience, waiting for the UI to catch up. I'm running the standard Human theme, so nothing wacky going on theme related that I know of.

Here's the original bug report, with fix, and my comments at bottom... https://bugs.launchpad.net/ubuntu/+source/gtk+2.0/+bug/331324


Running Jaunty 32bit, kernel 2.6.28-8 generic, Nvidia 180.29 proprietary driver standard repo version.

GTK+ packages are primarily 2.15.4-0ubuntu3 flavors, the current up-to-date packages from the Jaunty repos. The only exceptions to the gtk 2.15.4 packages seem to be libgtk2.0-cil (2.12.7-1ubuntu2), libgtk2-perl (1:1.190-1ubuntu1), and gtk2-engines (1:2.17.3-0ubuntu1).


Can anyone help? Launchpad bug reports are primarily oriented toward clear breakage, rather than performance issues, so I don't expect a great deal of response there.

Thanks!

Have you looked with the System Monitor to see what's eating the time?

Run "top" in the terminal, that will give you a clear indication of what is going on.

Nothing appearing System Monitor that jumps out... total CPU usage is around 40-50% minimum on each thread, but the individual processes don't add up to that amount. Largest running process is ~15% (the system monitor itself) and nothing else is eating processor time. It's a process that doesn't appear in the System Monitor for some reason.

This is on a PC at work... I will check using top tomorrow. Thanks for the help, guys, I will be back with you on it first thing in the morning (GMT-5).

Make sure you have View->'all processes' selected in System Monitor

Weird, whatever it is was solved in this morning's updates. I neglected to make a note of the packages.

It's zippy once again! No problems that I can see at the moment.

Thanks for your help, folks.
