Hi ,
I had a query regarding number of conn/sec in Haproxy and with regards to it
following are the details
*Setup*
Machine : Dual core AMD Opteron(tm) Processor 246
Mem:8GB
OS: Ubuntu 2.6.32-24-server x86_64 GNU/Linux
Request flow: HAProxy -> Varnish -> lighttpd ( All are running on same
machine )
Haproxy is running on port 2000 , varnish on 2001 and lighty on 2002
Benchmarking tool : Httperf
Requested object is of size 43 bytes
httperf --server=x.com --uri=/x.gif --port=2000 --rate=14000
--num-conns=900000 --num-calls=1
Specifying HAproxy port for benchmarking shows max conn/sec average of 8600
( httperf shows Errors: total 341739 client-timo 0 socket-timo 0 connrefused
0 connreset 0
Errors: fd-unavail 341739 addrunavail 0 ftab-full 0 other 0 ) whereas
specifying varnish and lighty ports show average conn/sec very close to 14k
with no such errors.
Is this problem with HAproxy setting ? How can the conn/sec for HAproxy be
bumped up to what varnish/lighty achieved in test results .
Following is the HA-proxy config
global
log 127.0.0.1 local0
log 127.0.0.1 local1 notice
