Examining varnishstat to see what happens. Varnish employs a kind of "slow-start" algorithm to thread creation which does not play well with synthetic loads like ab. Typically you have to precreate a suitable number of threads to avoid dropped requests while varnish ramps up. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 [email protected] | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. _______________________________________________ varnish-misc mailing list [email protected] http://projects.linpro.no/mailman/listinfo/varnish-misc
