Steps for Estimating the Server's Transfer Load
The transfer load refers to the quantity of data the server will need to transfer in order to accommodate the number of users that are likely
to download Web pages from the site. Calculating the anticipated transfer load helps identify the bandwidth requirements for the server and the site.
To calculate the bandwidth requirements for a server:
Transfer Load = (Web Page Size x 8 x Visitors) / 86,340secs
- Multiply by 8 to convert bytes to bits.
- Multiply by the number of visitors expected for the Web page in a specified time (usually a 24-hour period).
- Divide by the number of seconds in the specified time period (e.g. 86,400 seconds per 24-hour period).
Be aware that this formula only calculates the AVERAGE load over a 24 hour period. Most Web sites experience peak load times whose maximum transfer load requirements should be recalculated for just that specific period (such as 6 p.m. to 8 p.m.).
The following SlideShow illustrates how a server'a bandwidth requirements are calculated
Server Response Time
Server response time measures how long it takes to load the necessary HTML to begin rendering the page from your server, subtracting out the network latency between the search engine and your server.
