huh?I am a Project Manager and Computer Programmer with a 115 year old child welfare agency in Kansas. I basically schedule endless meetings and try to bridge the gap between technology and social work. Oil and water are better friends than those two. I have been doing this for just under 8 years now.
Before that I spent 10 years selling, building and servicing swimming pools. Hence the "poolman" part of my username.
Hey Stars, we recently added two new HP web servers and tested the load balancing capabilities of them. Both machines have 8 gigs of RAM and have dual quad core processors. (I think I am remembering that right, software not hardware is my speciality. might be quad dual core processors). We ran a full open T1 line to the servers and simulated 10,000 simultaneous users hitting the site (which is about 9,999 more simulateous users than we might normally see!) , doing full blown searches against a SQL2005 database, with pages with images that were 1.5 megs and higher.
The SQL server would occassionally spike to 60% CPU usage. The "load balancing" test never actually hit the load balancing stage since our first webserver didn't even hit 10% CPU usage! The ISA server never had to switch the load since the first web server handled it so well. Oh yeah, we ran this test for 15 full minutes before we pretty much came to the conclusion that either our webserver was a God and could handle any traffic, or that we were configured wrong and weren't possibly sending as much traffic to the server as we thought. I would be curious to know how you go about truly putting a heavy load on a server. We suspected that the ISA server was the bottleneck. We also wondered if a T1 was capable of sending enough traffic to bring the server to it's knees.
Be darned!......... I too, am from Topuka......... LOL
