RE: [squid-users] Aufs Problem???Syncing pending I/O operations.. (blocking)

hi Henrik,

No other processes running during working hours
All Cron Jobs are running night time.
Configuring Squid with options --with-aio-threads=N say 32 or higher will it
make any difference?
I thing 16 is the default?
Another thing searching old mail you recommended someone to use 'ulimit -Hn
4096' before running configure for performance reason it is something must
be done with Aufs?

Have you positively verified that there is absolutely no cron jobs
such as slocate updatedb which may start and bog down the server?

A single IDE should handle this relatively low load quite nicely I
think, but be careful to read the "5 minutes average" and not
"average since start".

No difference. What counts is the number of drives you have available
for cache, not how these are partitioned.

Then it can't be very old, only somewhat old. Probably overkill even.
