Hi, Well now my cachemgr is working I try to find why (if so) my proxy is slow sometime. so I find to big value that dose't look good to me: The first one it the avg service time of 1660.34msec for the External ACL statistic NT_global_group; did you agree with me that is way to high ? the other is some Reserved or Deferred request in the NTLM authenticator statistic menu the avg request is 1700/min, is that ok ? where can I look for other info ?
