Attached are the results of some benchmark comparisons between similar
systems. All of the machines have Triton chipset based motherboards, so the
only significant difference is async/pipeline-burst cache and the CPU speed.
-DG
90Mhz-async:
ASUS PCI/I-P54TP4, 32MB RAM, 256k async cache, Pentium 90Mhz
FreeBSD-2.1-stable (Oct. 9th)
90Mhz:
ASUS P/I-P55TP4XE, 64MB RAM, 256K pipeline-burst cache, Pentium 90Mhz
FreeBSD-current (Oct. 10th)
133Mhz:
ASUS P/I-P55TP4XE, 64MB RAM, 256K pipeline-burst cache, Pentium 133Mhz
FreeBSD-2.0.5-RELEASE
Note that on the 90Mhz machine, the source being compiled is 2.1-stable,
which should be very similar (in time) to the source in 2.0.5-RELEASE.
-pipe was used in all cases. All tests done twice (and the second time
was used) to make sure that everything was cached.
