Hi, I new to the squd-users list and I apologize if I am not posting correctly but I have been using squid for many years and this is my first post. I have read through the FAQs/Wiki and bugzilla database so see if this is a known issue or a configuration issue on my part but I am not finding anything relevant to "Median Service Time for DNS Lookups always being Zero". So I switched back to the 2.6-STABLE22 build line and it works as I expected. Median Service Times (seconds) 5 min 60 min: HTTP Requests (All): 0.03241 0.03427 Cache Misses: 0.12106 0.12106 Cache Hits: 0.00091 0.00091 Near Hits: 0.07409 0.07825 Not-Modified Replies: 0.00091 0.00091 DNS Lookups: 0.00094 0.00094 ICP Queries: 0.00000 0.00000 I would migrate from 2.6 to 3.0 build line but follow_x_forwarded is required for our installatons. I would appreciate any pointers or advice on what the issue is or if I am posting this issue to the wrong list.

The dns.median_svc_time = 0.000000 seconds is always 0 now matter and squid is processing request just fine. I an running Linux 2.6.9 kernel and did not have this issue on 2.6-STABLE22 and I am using squids internal DNS with out any issues. I just want to make sure that I don't have any issue before rolling out 2.7 to the rest of my squid servers. Here is an example from one of the 2.7-STABLE6 servers: Median Service Times (seconds) 5 min 60 min: HTTP Requests (All): 0.03066 0.03241 Cache Misses: 0.10857 0.10857 Cache Hits: 0.00000 0.00000 Near Hits: 0.06286 0.06286 Not-Modified Replies: 0.00000 0.00000 DNS Lookups: 0.00000 0.00000 ICP Queries: 0.00000 0.00000 Regards, Q
