Hi Vincent, I think your Squid server is starting with only 1024 file descriptors as shown by your logs above. Since you mentioned that you have a user base of 15000 and traffic utilization is increasing, 1024 file descriptors may not be enough. This could result in poor performance. However, since I have no experience regarding Solaris OS, your Squid may not suffer from running out of file descriptors. 2007/04/02 07:55:48| Successful DNS name lookup tests... 2007/04/02 07:55:48| DNS Socket created at 0.0.0.0, port 61044, FD 6 2007/04/02 07:55:48| Adding nameserver 10.66.122.32 from squid.conf 2007/04/02 07:55:48| Adding nameserver 10.66.67.3 from squid.conf 2007/04/02 07:55:51| Referer logging is disabled. 2007/04/02 07:55:51| Unlinkd pipe opened on FD 47 2007/04/02 07:55:51| Swap maxSize 3072 KB, estimated 2363076 objects 2007/04/02 07:55:51| Target number of buckets: 118153 2007/04/02 07:55:51| Using 131072 Store buckets 2007/04/02 07:55:51| Max Mem size: 409600 KB 2007/04/02 07:55:51| Max Swap size: 3072 KB 2007/04/02 07:55:51| Local cache digest enabled; rebuild/rewrite every 3600/3600 sec 2007/04/02 07:55:51| Store logging disabled 2007/04/02 07:55:51| Rebuilding storage in /ING/SQUID/var/cache0 (CLEAN) 2007/04/02 07:55:51| Rebuilding storage in /ING/SQUID/var/cache1 (CLEAN) 2007/04/02 07:55:51| Using Least Load store dir selection 2007/04/02 07:55:51| Current Directory is /ING/SQUID 2007/04/02 07:55:51| Loaded Icons. 2007/04/02 07:55:51| Accepting HTTP connections at 10.66.184.64, port 8080,
