ilSFV (Internet Link Speed File Verification) is an online service designed to help users verify the speed of their internet connection. It works by providing users with a test file that is downloaded from a known server. This test file is then used to measure the download speed of the user's internet connection. The results of the test are then displayed for the user to compare to the advertised speed of their internet service provider. This service is especially useful for users who are experiencing slow or unreliable internet speeds, as it allows them to easily pinpoint the source of the problem and address it with their ISP.
Discontinued The program is no longer updated. The latest version, 3.3, released in December 2007, can still be downloaded from the official website.
