Why is a direct socket-to-socket connection test more accurate than an HTTP test?
The difference in results is due to the different layers of the OSI model. A direct socket-to-socket connection works at the lower TCP transport layer. A HTTP connection uses a browser which works at the application layer and is subject to factors such as browser caches and proxies which can affect results, particularly on high speed networks (see the following FAQ). Socket-to-socket testing is available in MCS MySpeed Edition and the MySpeed PC Standard and Advanced Editions.
