Go into Cache Manager, under the NTLM Authenticator Stats page. This has the information you'll need to tune the number of NTLM helpers, as well as determining if the problem is not with Squid. Look at the per-helper statistics. The last few helpers should be basically idle (# Requests is low and Time is high). If not, add more helpers. If this is the case, then you need to look at other possible bottlenecks - disk/memory/CPU, network bandwidth, and possibly even your DC. Adam
