Hello!
I am Mr. Lee in charge of the operating the Squid cache server.
I have a big problem in our squid performance.
So, I need some solutions and recomendation to solve the probelm.
Please help me!
These followings are our squid information.

================= Information ==================
1. Platform & Squid Version
   o. Platform : SUN Enterprise 3000 (Total 2 ea)
   o. OS : Solaris 2.5.1
   o. Squid Version : Squid v1.1.17
2. Squid Server File System Info(per EP3000)
   o. Internal Disk (4 Gbytes) : Boot System & Squid Libray
   o. External Disk Array(Hitachi DF300-64GB) : Cache Directories
       8 LUNs - 16 File Partitions (Total 16 Cache Dirs)
3. Squid Usage Info(Per Squid System)
   o. Total TCP connections per day : over 2,000,000
   o. Connections per hour : over 250,000 (Peak time = 12:30 - 13:30)

4. Problem in Squid
   => Low Performance during peak time (12:30 - 13:30)
       We got the slow response time from squid, maybe I got the
messages - "Connected to ...." -
       over 1 or 2 minutes.
       So, I killed the squid processor very often. But, some minutes
later I must wait for very long time
       to get the "Connected to.." messages.
