Server Capability Calculator

Find out how much traffic your server can handle with this calculator. Given the upload speed it will calculate the maximum number of visitors you can handle. To allow for peaks the calculator takes a 300% overhead margin into account.

Tip: Save this page on your harddisk to use the calculator off-line.

Enter your requirements:
Server connection bandwidth Kilobit per second
Pages per visitor:
Page size: bytes
Overhead margin:
(100 is no margin)
 %

Traffic Megabyte per day
Gigabyte per month
Visitors Visitors per second
Visitors per day
Visitors per month
Pages Pages per second
Pages per day
Pages per month
Download time per page seconds
Simultaneous visitors

The calculator uses the following formula's:

Bandwidth =
ConnectionBandwidth * 100 / OverheadMargin
Traffic in Megabytes per day =
Bandwidth * 86400 * 1000 / (8 * 1048576)
Traffic in Gigabytes per month =
Bandwidth * 86400 * 1000 * 30.41 / (8 * 1073741824)
Visitors per second =
Bandwidth * 1000 / (PagesPerVisitor * PageSize * 8)
Visitors per day =
Bandwidth * 86400 * 1000 / (PagesPerVisitor * PageSize * 8)
Visitors per month =
Bandwidth * 86400 * 1000 * 30.41 / (PagesPerVisitor * PageSize * 8)
Pages per second =
Bandwidth * 1000 / (8 * PageSize)
Pages per day =
Bandwidth * 86400 * 1000 / (8 * PageSize)
Pages per month =
Bandwidth * 86400 * 1000 * 30.41 / (8 * PageSize)
Download time per page =
PageSize * 8 / (Bandwidth * 1000)
Simultaneous visitors =
60 * Bandwidth * 1000 / (PageSize * 8)
