[K12OSN] Impress/Firefox very, very, very slow

[dahopkins at comcast.net]

Top shows impress and firefox taking most of the cpu on the system (with beagleindex intermingled as well at times).  The system is dual 2.4Gz Hyperthreaded Xeon with 4Gb memory, Ultra320 18Gb drives.  Fedora core 4 (k12ltsp 4) ran very well, but ... upgraded at start of year and have had issues off-and-on ever since.  Issues only show up under load (more than 5 users)

I am downloading patches for SO8 and will apply them as well (340Mb download)

Sincerely,
Dave Hopkins
