Re: [squid-users] Squid CPU Performance
Hi! I have a squid server for 6K users. the machine is a HP-lpc 2000 dual 1Ghz, 4Gb ram and with 2 raid1 one for the os and swap, the second for cache. The only performence loss for my machine is at monday morning when every user begin at there work and it slow downs the machine for about 10 min but they can sill surf with slower speed...

I tested this exact server config with 74 users and performance was pretty good for 800 Reqs/Min. Now in Production I have 325+ users at 2700 Reqs/Min and performance stinks. It's like being on a dial-up connection. 3 of the procs are sitting below 1%. The other is used by Squid at 99.9%. It there any way to speed up performance on a multi-proc system? TIA. not really... it will however go a lot faster if you unraid the 3 9gb drives and treat each one as a seperate cache dir...

Re: [squid-users] Squid CPU Performance
b) Squid is the worst case application for RAID5 and will absolutely kill the performance of a RAID5. RAID1 is fine, and so is separate drives. And if I use Logical Volume Manager? I use EVMS in my linux system, http://evms.sourceforge.net/. EVMS is like LVM. I have 3 scsi disks seen as a single storage volume. Thanks to EVMS, or LVM, I can expand dinamically single directories when necessary. I think that using LVM for all the 3 scsi disks I can't have the performance as using single disks. Isn't it? Sorry for my english.
[squid-users] Squidalyser 1.0b search criteria
Hi Fellow Listers, I was trying out Squidalyser 0.2.55 and v1.0b. I managed to install and test the first version except that I did not like the interface that it comes with. I therefore decided to try the Beta version and succeeded in installing and configuring it after battling with CGI and DBD and my Perl in general. Now the problem is that I can't seem to get to use the search criteria. Whichever combination I use seem to yield no match/result - even the most global search. The squidalyser database in Mysql is populated with my most recent access.logs. I downloaded the source from http://www.ababa.org and was able to find an installation guide but no user guide. Someone help! Ralph
[squid-users] Security when using public Squid proxy
Dear all, By using a public Squid proxy, in IE, i type ftp://123:[EMAIL PROTECTED] If they enabled logging in Squid proxy, are they able to know the user name and password when accessing private ftp? Thanks a lot!

[squid-users] redirect_children not independent ??
Hello, I have squid running with squidGuard as a redirector and ncsa_auth for authentication. I have put some debugging hooks (mostly some counters) in the squidGuard code, and find that even if I start multiple sessions with different userIDs under squid, all the squidGuard sessions share the values for the counters. That is, if I start a session in squid and goto five (5) blacklisted sites, one of my counters has moved to five (5). Then if I start another squid session for a different user (while the first one is still active), the counter for blacklisted sites visited is set at five (5) from the first session, and if the second user visits a blacklisted site, the counter moves to six (6). So it appears that both sessions visited six (6). This seems to imply that the redirect_children are not really unique threads from squid, is this correct? Thanks, Murrah Boswell
