with WOLK v3.6 and only ONE harddisk drive:
root@codeman:[/] # du -skh /home 605M /home root@codeman:[/] # find /home|wc -l 7384 root@codeman:[/] # time mkisofs -o /delme.iso -allow-multidot -iso-level 3 -J -max-iso9660-filenames -U -R /home ...
real 1m12.872s user 0m1.840s sys 0m10.800s
with one big file:
root@codeman:[/] # du -skh /home/onebigfile.delme 620M /home root@codeman:[/] # time mkisofs -o /delme.iso -allow-multidot -iso-level 3 -J -max-iso9660-filenames -U -R /home/onebigfile.delme ...
real 0m35.676s user 0m1.180s sys 0m10.740s
:-)
Anyway, I also tested the patchset from Con, both, with -aa VM and -rmap VM and I must say, -rmap is much slower than -aa VM.
Testmashine: Celeron 800MHz 256MB RAM 1x Seagate 30GB running in UDMA4 (ATA66) mode Filesystem: ext3, data=ordered
I think with your mashine this could be a bit faster also ;)
