well, i see the same problem as everybody here: i've had some corrupted
reiserfs systems, and it wasn't possible to restore the data (except
backups of coures ;)). We're still running reiserfs on our proxy servers
(squid), but we have the phenomenon that the machines get slower and
slower while squid is running, and if you stop squid and wait some time
and start it again it all goes fine again. but the problem isn't squid,
it seems to be reiserfs which seems to be not able get all data written
to disk in time and slows the computer down. (sure this also depends on
the harddisks, but we played around with hdparm and the situation was
exactly the same with DMA enabled (140MB/s) and disabled (4MB/s), so it
cannot be the HDD).

I'm confused. How does measuring sequential read/write performance map to squid performance? Doesn't squid usually do lots of little read/write ops, with lots of seeks too?
