[squid-users] Strange latency from Squid 2.5 to Squid 2.6

Hi!

I've changed my old server gateway/proxy with Squid 2.5 STABLE14, with
a new Proxy server with Squid 2.6.STABLE18 (Ubuntu 8.04LTS).

Now I have low reply from some text-page (CGI-BIN) of intra-vpn site.

Also "tcpdump" show a latency not present with old squid or directly
without new proxy!

Heare a dump with 4 sec of wait for reply.
