FWIW, I'm running 2.2.12-13pre14 + Uniform IDE + NFSv3 / RedHat 6.1beta on a
bp6 with two 466a celerons (no overclocking), 256MB Micron ECC RAM, a
27GB WD ATA-66 drive, a Viper V770 TNT2 AGP card, and Netgear Tulip
fast ethernet cards (don't buy the newer Netgears; they're cheap
clones!) in a room whose ambient temperature is 70F/21C. The
temperature sensors hover under 40C.
This machine has been solid since I built it.
The memory bandwidth is a bit anemic due to the 66-MHZ FSB, but I was
loathe to overclock slower Celerons like the 300a by 50%. (My
understanding is that one needs to boost the FSB to 100 MHz in order to
allow the PCI and AGP busses to operate in spec; otherwise, everything
will increase proportionately.) I built this machine as a cheap box to
do SMP QA, and it does this admirably.
The STREAM benchmarks look like this:
Function Rate (MB/s) RMS time Min time Max time
Copy: 203.7101 0.0791 0.0785 0.0799
Scale: 203.4380 0.0788 0.0786 0.0791
Add: 241.3493 0.0997 0.0994 0.0999
Triad: 223.4220 0.1076 0.1074 0.1080
hdparm and bonnie report >20 MB/s (thanks to Andre Hedrick!) and I
simultaneously compile 2.2.x and 2.3.x kernels, run NFS client <-> server
tests over the loopback interface (like cpio -pdum ), and surf the web
using Netscape.
Next job is to get 2.3.x USB going; I'm buying a USB digital camera today.
