Most of the 1 GHz Athlons use the VIA chipset. You do NOT get proper performance from the 2.2.19 kernel on the VIA chipsets, as you can not get UDMA66/100 to enable properly. On the 2.4 kernel it appears to work flawlessly. Definitely, you can expect disk I/O performance problems using the 2.2.19 kernel with just about any Athlon system. This is ALL assuming IDE of course. Since the original poster did not specify, it is fairly safe to assume such. Somebody with SCSI and/or RAID would usually know to say so.

We need more info Bob! :-) I'd say throw a couple stick of DDR2100 in and don't worry about it. What version Athlon is it? 200 or 266 FSB, how much cache? (I know stock athlons get 128K L1, but I've seen then with 384.) What kind of motherboard? AJ's 1ghz machine w/ scsi disks is by far the fastest desktop in our office, it just hauls ass. -- Thomas J.
