In one line: everything seems OK.
Pehaps you want some details ;)
Kernel 2.4.22 (from kernel.org) compiled with gcc2.95.4-debian/stable
with the config file from 2.4.21-xfs provided in knoppix3.2-2003-07-26
(it contains everything you want)
Mother board Abit BP6 (dual celeron 400 + 512Mo)
+ hpt366 UDMA4 controler + 80Go Maxtor
The kernel doesn't activate UDMA during boot, with my hpt366 , so I use
# hdparm -p -X68 /dev/hde
# hdparm -d1 /dev/hde
and I am in UDMA4 +/- 30 MB/s of sustained transfert :)
I had 3 compressed images of 600 Mo made with the new tools (1.02)
(the first 3 iso of debian stable)
and the fourth of 1.7 Go , made whith mkisofs | create_compress_fs_1.02
Your stress test:
------------------
for i in 1 2 3 4; do
tar cpPf - /mnt/cloop$i | dd of=/dev/null &
sleep 10
tar cpPf - /mnt/cloop$i | dd of=/dev/null &
done
With 512 Mo RAM, the load goes up to 8.1, the 2 CPUs are used
and it goes very fast:
more or less 3MB/s for _each_ dixit dd
xosview said disk-read=17MB/s
My memory usage was:
+/- 64 Mo for my base system
the rest of the 512 Mo for cache
no swap usage
neither dmesg nor /var/log/messages said noticeable things.
I could even still do small things in an xterm (man ...)
So it seems to be nice :)
Greeting
Alain
