Comment (by kargig):

 I have been running branch bug12160_024 for more than 10 days, and I was
 unable to get the Fast flag using the haproxy setup
 {{{
 ORPort 443 NoListen
 ORPort 127.0.0.1:444 NoAdvertise
 }}}

 As soon as I switched to a setup without haproxy in front:
 {{{
 ORPort 443
 }}}

 I immediately got the Fast flag in less than a day.

 I am pretty sure haproxy is not the bottleneck is this setup because it's
 designed to handle thousands of tcp connections really really fast. If I
 add the relay in an EntryNodes line in my client it seems to be working
 properly in either setup.

 Can you advise on how I should proceed with debugging this ?
