The only way is to increase the number of ntlm authentication helpers that you're running; but hm, you're using 150 ntlm authentication helpers. There's a page in cachemgr - again, I forget its name - which gives you the authenticator statistics (helper status, queue length, etc.) Hm, if you file a bugzilla request I could come up with a way of getting access to the queue statistics. There's a project on http://devel.squid-cache.org/ - the auth ip cache project, I forget its exact name right now - but it'll help quite a bit. It breaks if you need to use cache peers as it caches the results for each client IP address. Hm, I think I know how to fix that too, somewhat. (Henrik, what about using ACLs to mark which clients can have their auth info cached?) Adrian -- - Xenion - http://www.xenion.com.au/ - VPS Hosting - Commercial Squid Support -
