Configuring maximum simultaneous requests

You can set the number of maximum simultaneous requests, which is the number of active requests allowed for the server at one time. However, for general purpose Internet or intranet use, you probably will not need to change the default value (128 requests).

To get the number of simultaneous requests, the server counts the number of active requests, adding 1 to the number when a new request arrives, subtracting 1 when it finishes the request. When a new request arrives, the server checks to see if it is already processing the maximum number of requests. If it has reached the limit, it defers processing new requests until the number of active requests drops below the maximum amount.

In theory, you could set the maximum simultaneous requests to 1 and still have a functional server. Setting this value to 1 would mean that the server could only handle one request at a time, but since HTTP requests generally have a very short duration (response time can be as low as 5 milliseconds), processing one request at a time would still allow you to process up to 200 requests per second.

However, in actuality, Internet client frequently connect to the server and then do not complete their requests. In these cases, the server waits 30 seconds or more for the data before timing out. Also, some sites do heavyweight transactions that take minutes to complete. Both of these factors add to the maximum simultaneous requests that are required. If your site is processing many requests that take many seconds, you may need to increase the number of maximum simultaneous requests.

If you need to change the number of maximum simultaneous requests, set the number before starting the server. To reset the number:

  1.Choose Server Preferences|Performance Tuning.
  2.Type the number of requests.
  3.Click OK.
  4.Click Save and Apply.
