Hi,
We are testing a setup which has a local haproxy which connects to a remote
haproxy which in turn calls an apache server which returns a html page.
Haproxy(local)->Haproxy(remote)->Apache.
We have the set up working, the ping time from local to remote haproxy is 204
ms.
The time taken for the web page when accessed by the browser is 410 ms.
We want the latency to be 204 ms when accessed by the browser. We configured to
reuse http & with http-reuse aggresive|always|safe options
but could not reduce the 410 ms to 204 ms. It is always 410 ms. Please let us
know how we can reuse http & reduce out latency.
Thanks
Karthik
