Hello,
I'm running ATS in front of a fairly large *shared* webserver (many
vhosts). I've noticed that with keep-alive Traffic Server keeps a two
level hash of established sessions: ip -> hostname -> session. Because
of this ATS opens way too many connections than are needed.
In HttpSessionManager.cc I found this comment which explains the
reasoning behind this:
// We compute the mmh for matching the hostname as the last
// check for a match between the session the HttpSM is looking
// for and the sessions we have. We have to use the hostname
// as part of the match because some stupid servers can't
// handle getting request for different virtual hosts over
// the same keep-alive session (INKqa05429).
Do you know which servers were affected by such bug?
I made a small patch to disable the 2nd level hash and noticed a huge
performance benefit under heavy load. Would it be possible to have this
as an option in records.config?
