Yeaaa, I would expect it too :(

The machine is really stable and serve 5 users with KDE, mail, X Window 
server, LTSP server, print server.

time bzip2 final.mpeg -c > /dev/null
real    10m14.901s

sys     0m4.400s
Note that final.mpeg is ordinary movie mpeg file  - 644,5 MB size.

I thing it is working streamless.
zeus:~/main # hdparm -Tt /dev/hda

/dev/hda:
 Timing cached reads:   1748 MB in  2.00 seconds = 873.95 MB/sec
 Timing buffered disk reads:  166 MB in  3.02 seconds =  54.96 MB/sec
zeus:~/main # hdparm -Tt /dev/sda

/dev/sda:
 Timing cached reads:   1820 MB in  2.00 seconds = 909.94 MB/sec
 Timing buffered disk reads:  174 MB in  3.02 seconds =  57.54 MB/sec

gcc version 4.0.2 20050901 (prerelease) (SUSE Linux)
I compiled xvidcore-1.1.0.tar.bz myself now.
Still SLOW, SLOW...

I tried this one, without frameno:
mencoder -noaspect -oac mp3lame -lameopts vbr=3:br=96 -ovc xvid -xvidencopts 
bitrate=1000:vhq=1:me_quality=6:trellis:chroma_opt:max_bframes=0:hq_ac:pass=1
../$file -o $file-final.avi
butt SLOW SLOW... 7 frames / second
