Adding nbproc 4, improved performance of https from 511 req/s to 1296
req/s..
not quite an exponential scaling..
We tested with 8 cores and got 1328 req/s.. so it seems we're hitting
"something else" already after 2,5 core..
vmstat 1 - also reveals a lot of cpu-idle time..

Hi guys,
I'm testing our haproxy setup in regards to SSL performance - by
simply using ab, and fetching a favicon.ico file..
over http haproxy delivers 3.000 req/s.
over https haproxy delivers 511 req/s.
I tried giving haproxy more cores (it's a virtual server) -but this
did not help at all :(
Silly question: when you added more vCPUs to the virtual machine
did you change haproxy nbproc setting (make haproxy use more than
1process) ?

I can't seem to find anything on haproxy actually hitting a
bottleneck.. I did try to do the https test from 2 clients
simultaneously- and then they just get half the req/s - so total is
the same.
What should I look at, to improve https performance in haproxy?
