Hi All,
I've got a working HAProxy setup however with a strange issue.
Every now and then we get client responses that take anywhere from 15-60
seconds for pages that are processed very fast on the server side. The page
partially renders and is 'waiting' for the rest of the content which eventually
filters in. I've witnessed the response on the server side and it's completed.
It also only happens with then are 'multiple' servers configured, any clients
with a cookie for the additional servers get the intermittent slow response.
The slow response is also very intermittent. A client could actually use the
site and never encounter it.
I have analyzed our application and rebuilt servers in an attempt to fix this
to no avail.
I realize that this a pretty open ended post but am wondering if anyone has any
ideas on why this would be occurring.
We are using stunnel for SSL termination however that is for only 2 pages in
the site.
