I would agree with this.  If you have a little money to spend, invest
in some RAM and/or a CPU upgrade. My system (an 8500 running Woody and
a 2.4.20 kernel built from kernel.org sources) has similar HD numbers
as yours, i.e.

/dev/sda:
 Timing buffer-cache reads:   128 MB in  2.10 seconds = 60.95 MB/sec
 Timing buffered disk reads:  64 MB in 12.76 seconds =  5.02 MB/sec

/dev/sda:
 Timing buffer-cache reads:   128 MB in  2.10 seconds = 60.95 MB/sec
 Timing buffered disk reads:  64 MB in 12.71 seconds =  5.04 MB/sec

/dev/sdb:
 Timing buffer-cache reads:   128 MB in  2.11 seconds = 60.66 MB/sec
 Timing buffered disk reads:  64 MB in 11.82 seconds =  5.41 MB/sec

/dev/sdb:
 Timing buffer-cache reads:   128 MB in  2.10 seconds = 60.95 MB/sec
 Timing buffered disk reads:  64 MB in 11.80 seconds =  5.42 MB/sec

(both 4.5 GB 4200 or 5400 RPM drives, can't remember right now).  But
I have a G3 375 MHz CPU (512 KB L2 cache) and 1 GB RAM, and those let
me get kernel compile times under 20 minutes.
