I have two different proxy servers on our network, the one is currently in production (linux 2.4.17, squid 2.4Stable1, ext2 file system) and doing no auth. The dev (linux 2.6.9, squid 2.5Stable9, reiserfs file system) server is doing ntlm auth against a windows NT server. When I download the same file at the same time from the current production server I get speeds of avg 10 kb/s and on the dev server it stays at about 550 b/s. Both servers are using the same link. Could the auth be slowing down the download to that extend? Or what should I actually be looking for? Paulo
