Determining HTTP thread requirements

To determine how many HTTP threads are required, check the request pattern in the httpstat.dat file for indications of a heavily loaded server. Adjust the maximum thread setting as necessary. Ideally, this setting should be 10 – 20% more than the number of simultaneous HTTP requests that you expect to handle. (The additional threads accommodate the use of threads in Web browsers to submit simultaneous requests for images and text). A value that is too low can increase HTTP response time by causing requests to block while waiting for a thread. A value that is too high wastes available threads that could be used for other purposes.
