[squid-users] Number of threads in AUFS

First, my system is:

RedHat 9 (2.4.20-20.9)
1.8GHz Xeon * 2
SEAGATE ST373307LC (10000 RPM, U320 SCSI) * 2
Memory 1G
Apache/2.0.48

Squid version : 2.5 STABLE4

HTTP request generator : httperf 0.8 (with 200 req/s)

I compile Squid with options :
--with-aufs-threads=32 --with-pthreads --enable-storeio=aufs

Corresponding to the configure option, i think that there are 32 threads of
Squid, but :

ps -ef | grep squid
root 5906 1 0 Feb18 ? 00:00:00 sbin/squid
nobody 5908 5906 0 Feb18 ? 00:00:03 (squid)
root 8271 5505 0 14:45 pts/0 00:00:00 grep squid

There is only one Squid process and its child, respectively.
(There is no change in the number of process when I start httperf: sending
HTTP requests - 200 req/s)

Therefore, i've searched the mailing-list, and found this:
http://www.squid-cache.org/mail-archive/squid-users/200303/0520.html

According to the answer, my system do not operate any disk I/O action.

To help your understanding about my situation,
i append the latest contens of my cache.log file below:
