I guess we should start helping the root guys out a bit. I highly recommend you find out where that .localdomain comes from and get it changed to .local or your real domain name. Even getting it changed in resolv.conf to "search .local. yourdomain.example.com" would be better. > 2010/02/14 21:34:57| Unlinkd pipe opened on FD 10 > 2010/02/14 21:34:57| Store logging disabled > 2010/02/14 21:34:57| Swap maxSize 0 + 262144 KB, estimated 20164 objects > 2010/02/14 21:34:57| Target number of buckets: 1008 > 2010/02/14 21:34:57| Using 8192 Store buckets > 2010/02/14 21:34:57| Max Mem size: 262144 KB > 2010/02/14 21:34:57| Max Swap size: 0 KB > 2010/02/14 21:34:57| Using Least Load store dir selection > 2010/02/14 21:34:57| chdir: /var/log/squid/cache_instance0: (2) No > such file or directory Highly suspicious ... chroot'ing to a non-existence directory? > 2010/02/14 21:34:57| Current Directory is /usr/local/squid/etc > 2010/02/14 21:34:57| Loaded Icons. > 2010/02/14 21:34:57| Accepting HTTP connections at [::]:200, FD 11. > 2010/02/14 21:34:57| HTCP Disabled. > 2010/02/14 21:34:57| Squid modules loaded: 0 > 2010/02/14 21:34:57| Ready to serve requests. > 2010/02/14 21:34:58| storeLateRelease: released 0 objects > 2010/02/14 21:43:34| Preparing for shutdown after 386 requests Second most suspicious.

By "turned off" you mean: * you have no configured cache_dir entries? * that you configured "cache deny all" ? * that you shut down Squid? Unless you cache objects in transit there is no speed gain. There is some slow down while squid processes things before passing them on. Working without Squid will not have to do that extra processing, so will seem faster when just passing packets on. The speed gains from Squid come when an object is fetched from some local cache instead of from the Internet pipes. Yes. I would expect an encrypted filesystem to work slower than a non-encrypted one. Amos
