OK, this is what I've done. 
for i in `seq 100`; do tar jxf linux-2.5.41.tar.bz2 ; rm -fr linux-2.5.41 
; done 

and started copying a 571MB ISO image at 10x, then I've started mozilla, 
opened some pages with flash and java, xmms came next, I'm listening to 
mp3 (not a single skip, it used to skip in the "Fixating" part with 
ide-scsi)... ah, and I'm reading email using Evolution. Everything under 
Gnome 2.0 (RH 8.0)

Track 01:  571 of  571 MB written (fifo 100%) [buf  99%]  10.6x.
Track 01: Total bytes read/written: 599654400/599654400 (292800 sectors).
Writing  time:  400.083s
Average write speed   9.9x.
Min drive buffer fill was 73%
Fixating...
Fixating time:   27.454s
cdrecord: fifo had 9446 puts and 9446 gets.
cdrecord: fifo was 0 times empty and 8430 times full, min fill was 76%.

This is a lot better than with ide-scsi, system felt smoother also.

Specs:
Celeron 600Mhz
256MB RAM
cheap mobo, cheap disks UDMA66 and UDMA33 
hdb: Hewlett-Packard CD-Writer Plus 9300, ATAPI CD/DVD-ROM drive

tar was done in the same disk in which ISO image is. I'm using ext3 
data=ordered

The only annoying thing is that if I left the drive without a disc my 
syslog get flooded with end_request: I/O error, dev hdb, sector 0 
messages, but I guess this is somewhat related to nautilus.
