Hey, I'm writing a program to test the performance of apache (we had a similar problem with lighttpd), and I keep running into a problem with persistent connections. We make a single request, like: GET fileName HTTP/1.1 Host: server:80 Keep-Alive: 300 Connection: keep-alive And we get a response back. We then make another, similar request on the same connection, and we get a response back, but there's a huge delay in-between sending our request and getting the response for the second request. To give you an idea of the times: request 1: sent at 0 ms, received at 1 ms request 2: sent at 1 ms, received at 41 ms request 3: sent at 41 ms, received at 81 ms request 4: sent at 81 ms, received at 121 msAnd we see this 40 ms delay all throughout after the first request. Clearly it doesn't take that long to deliver the file, so we're not sure what gives...why the
delay? Just FYI, we're testing on a high-bandwidth, low-latency network. Also, we do HTTP pipelining, and when we send all these requests at once on one connection, we get the response back extremely quick--we're just not sure why the 40 ms or so delay between requests on the same persistent connection and not on the pipelined connection. There's almost no lag between the machine, so we're not sure what's up.Is this something apache and lighttpd do to make sure people don't request too much.
Is this a setting we can change? Thanks, Ryan --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
