squid with reiserfs

Hi!

So far, reiserfs looks really quite promising. I now switched all for
proxies we have to reiserfs.
They are still building up their caches (as of course I had to delete the
cache to convert the drive to reiserfs) but so far it really looks as if
they would be running quite a bit faster and with less cpu load.
Here are some stats of the box that is running reiserfs for the longest time
now (about 24 h, but squid has been restarted in that time). It a P II 333
with DPT Raid Controller with 64 MB RAM and I think 4 Harddrives:
