I'm get slow performance from BM in a computer lab when they use maps.google.com and start zooming in and out.
The site works fine if it is just one or two computers, but when there are 20 or so it bogs down.
I have a new HP DL140 with 3.8 border manager with 2mb ram and 2 scsi hard drives ( 1 for sys and 1 for cache)
I have used Craig Johnson's tuneup.ncf file for the settings.
