I have a question about connection pooling. We are running an ASP.NET site, and I have found a lot of information on connection pooling, like you can get connection pooling if you use the same connection string, you can specify the Max Connections (which we never did) and what not. We were recently stress testing a site of ours. We would put a load on the web servers (local) and everything seemed to work fine. If we tested one of our web servers, we would get about 800 requests a second, if we tested two we would get about 400 requests a second on both, if we tested three we would get about 260 requests a second. (Everything seems to cap off at about 800 requests a second) This baffled us because the servers seemed like they could handle more. Their processors were all at about 30%, memory is fine, and the database server was fine. My Question: Because they all use the same connection string, are they all sharing the same pool of connections? Does connection pooling take place on the Database Server, or the web server? Unfortunately I can run any tests right now, I just wanted to get your input on possible problems, solutions.
