Dear List, I have a feeling that PF can't do perfect round-robin load balancing over 100Mbit. When our PF server's (Dual Quad Core 3Ghz with 8GB ram) network traffic goes over 100Mbit, the 80 port's connect time increases to 3-5-10 sec instead of the stable 0.001-0.002 sec. The web servers feel good, they don't have load, the redundant master-slave database servers feel good, they dont have high load. So everything seems fine, except the connect time. (Our checker script asks only a HEAD request from the web servers) The internal network has Gbit connection so as the internet side. Do you have any advice? Is it time to get a Layer 7 switch and do load balancing with it? Or is it possible to do it in a PF way without a Content Switch? 2 web servers and 2 database servers are involved. [web 1] ---| [web 2] ---| [db 1] ---|---[pf/web 3/default gw]---internet [db 2] ---| For a while the web server on the PF server is down to test, but it does the same connection time with a running apache and without a running apache. Any idea? Our internet traffic average is 100Mbit-130Mbit and the connect time makes me so sad.
