# Estimating Request Traffic

This topic explains how to measure and set the number of daily connections you anticipate for your site. If the number is set slightly higher than the actual number of connections, the connections are made faster and server performance is improved. If the number is set much greater than the actual connection attempts, server memory is wasted, reducing overall server performance.

To determine the number of daily connections to your server

1. Use System Monitor to log the value of the Total Connection Requests counter and the Current Connections counter, both of which are in the Web Service object.
2. Collect data in log files for several days if possible, to get a realistic record of the conditions that your server experiences.

Note Some connection requests may fail, so the Total Connection Requests counter is not necessarily fully accurate.

To set the number of daily connections from your estimate

1. In the IIS snap-in, select the Web site and click the Properties button to display its property sheets.
2. On the Performance property sheet, set the value slightly larger than the estimated number of connections you anticipate receiving in a 24-hour period.
