Re: Configuration of Host OS for maximum speed.
Go to that machine and type ulimit -n -mox On Thu, Apr 21, 2011 at 1:20 AM, Stijn Vanhoorelbeke stijn.vanhoorelb...@gmail.com wrote: Hi, I've installed HAProxy onto an 32 bit Ubuntu Server OS. Are there special parameters I should take care of - in order to achieve maximum performance? Also, are there any special HAProxy start-up parameters I should take care of. I want to be able to serve 2000 concurrent connections. The front end section of HAProxy goes up to 2000 - but the backend servers ( total of all backend servers) only aggregate something around 1000 concurrent users. I cannot achieve higher backend values - even if I add an extra machine to the haproxy pool. Anyone got an idea how this comes?
HAProxy pconn question
From what I can tell via Docs + The Great Googletm I see that HAProxy seems to work in three ways for HTTP/1.1 persistant connections. 1) Full keep alive, 1:1 mapped client-server. All requests go to the same server. 2) option http-server-close Keep client side open, shut down server side. 3) option httpclose Shut down both server and client side. I am looking for something which will keep m-servers AND n-clients connected, but which will balance around the open connections between two realms. Once the clients and servers are connected I would like to balance them without rebuilding ANY of the sockets on either side. Does HAProxy support this in anyway that I have not seen, hopefully in the L3/4 area and not using HTTP/1.1 keep alive semantics? TIA! -mox
