The error log is empty! Is there some sort of limit put on number of requests allowed from external host? I just tried
ab -n 100000 -c 300 http://localhost/ and it did not show the "drop dead" behavior after a certain period of time. However local benchmarking seems to have a ceiling of its own, once I increase the concurrent users to 500 it gives apr_socket_recv: Connection reset by peer (104) But at least 500 is a lot higher than 50. I hear apache is capable of serving thousands of requests per second, what am I missing?

Did the error log say something? It surely will have something incase its not able to find any resources or breached any limits!

I am using both ab and siege against apache to try to find out how many users can be loading a specific page at a time. I find that if when concurrent connections are set to anything above 50-100, the server will run fine for 5-10 seconds but then completely stops accepting new connections after that. All connections from ab and siege returns "connection time out". The higher I set the concurrent users, the faster this happens. If I set it to 1000, it happens almost immediately. It is as if the server has ran out on something. But I am not sure what, ran out of sockets? Cpu usageis showing as 2% and plenty of memory. Also this is done over LAN so the network is not the limiting factor. Surely apache must be able to handle over 100 simultaneous connections at the same time? My application will probably have more than 100 users making request at the same time. Any ideas? What command should I be using with ab/siege to properly probe the maximum request/second? PS. so far I am only benching the default page (ie. welcome to apache...)
