I can't really say which of the 10.4.point OS versions is faster, I think 10.4 and 10.3 both ran really well on my G3 with the 1GHz G4 upgrade. Definitely better than 10.2. 10.4 seems faster, but that may be due to my striped RAID I'm now using, booting and launching apps is pretty responsive.
In the too-much-information department...but since you asked, here are some of the peak numbers (uncached sequential read 256K blocks) from
Xbench tests, not sure how good a test this is, but results will always vary a little from test to test. Is anyone getting much better performance than this, and if so what are you using?
For the G3 Desktop: (some tests were done in earlier configurations of my machine that no longer match the config listed in my signature)
15 MB/sec on built in

45 MB/sec: 120 GB Maxtor 6Y120P0 ATA/133 7200 RPM on PCI-ATA66
47 MB/sec: 120 GB Seagate ST3120026A ATA/100 7200 RPM on PCI-

70 MB/sec: SeaMax 120+120 on a PCI-
ATA66RAID, I know the drives don't match, but hey, they're close enough.
My MacBook:
43 MB/sec: 160GB 5400RPM Hitachi HTS541616J9SA00 SATA
Is there a better benchmark utility to measure hard drive speeds? I am surprised the MacBook isn't faster with the SATA drive.
