Yeah, I always work with the system monitor in the top bar on Gnome. It's the observations I'm making in the system monitory that are leading me to believe my problem is disk IO. Just watching the browser try to access it's cache is painful. And also, that background indexing always seems to start at the wrong time (when I'm in the middle of something else). Is there any way to do that manually instead? > From: Matthias Johnson <[email protected]> > To: [email protected] > Subject: Re: [mhvlug] Ubuntu performance problems. > > Kris just curious is there anything revealing using top or stuff in ps aux? No, top and ps are both reporting CPU and mem usage like I'm used to seeing. > Also as a side note on many dell and other vendors I have seen issues where > the harddrive drops significantly in performance as time goes on but doesn't > actually die.

This is a stock Toshiba drive in a 5 yr old Toshiba laptop. I'm going to repartition, format, and reinstall Ubuntu to see what happens. -- Kris _______________________________________________ Mid-Hudson Valley Linux Users Group http://mhvlug.org http://mhvlug.org/cgi-bin/mailman/listinfo/mhvlug Upcoming Meetings (6pm - 8pm) MHVLS Auditorium Jan 5 - Building a Community Site with Drupal Feb 2 - Zimbra Mar 2 - MHVLUG 8th Anniversary - Show and Tell
