Hello Amos and thank you! >> sinec i upgraded two Squid proxy servers to the Squid-3.4.4 versions, we have some huges bottleneck with ahtenticated ntlm (old style!) users. >> If i disable authentication and enable per-ip surf, it works fine. >From what earlier version? I did upgrade from the 3.1.8 version (in that ntlm worked fine for us). >3.4.4 is very outdated version of Squid. Current release is 3.5.12 or >3.4.14. OK, we will upgrade to latest 3.4.x! But why n 3.1.8 NTLM (with the same squid.conf) worked fine? Thank you again!
