That stuff is irrelevant. The kernel and glibc are set up for i686 (kernel also for athlon, etc.) and those provide the biggest benefit. > I've gone into my BIOS and knocked down the memory for the AGP aperture > from 128MG to 64MB.

If you have 256MB and share 64MB to AGP, then you should have an "append" line like this... append="mem=192M" Personally, unless you are running mostly movies, or 3D gaming, I would cut the shared memory down even further. 16MB for general pupose use is plenty. Just adjust the append line accordingly. > Is there some setting somewhere for bus bandwith or something? I noticed > this IDE is running with a "default" of 16. Should it be 32?

To set the proper I/O support simply put in... hdparm -c1 /dev/hdx (where x is the drive letter) What speed is the SCSI bus? If you get readings that are ~75% of what it is rated at then it is fine. > It could just be that RH 8.0 and all the new stuff is just a slower dog on > the same machines, err like Windoze is. It's not "bloat". Each new version has improved performance for me. GCC 3.2 did wonders. I think it mostly has to do with differences in the kernel and XFree86 drivers. For example the Phoebe beta broke video support on one of test machines (I hope it gets fixed). -- Brian Ashe CTO Dee-Web Software Services, LLC.
