Hell Bryan, Thank you for the response. I have replied inline.

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. 4. Local haproxy log 172.31.x.x:53202 [26/Oct/2017:21:02:36.368] http_front http_back/web1 0/0/204/205/410 200 89 - - ---- 0/0/0/0/0 0/0 {} "GET / HTTP/1.0" This log line says that it took your local proxy 204 ms to connect to the remote proxy and that the first response bytes from the remote proxy were received by the local proxy 205 ms later for a total round trip time of 410 ms (after rounding). The only way to get the total time to be equal to the network latency times would be to make the remote respond in 0 ms (or less!). If the two proxies are actually 200 ms apart, I don’t see how you could do much better. -Bryan Yes the log indicates that. But the RTT via ping is 204 ms, with http-reuse always/aggressive option the connection is reused & we expect a time close to ping+ a small overhead time, the http-resuse always seem to have no impact on the total time taken. We are looking to get the option working. Thanks again! Best Regards Karthik
