Editors' Review

by   / February 27, 2009

SG TCP Optimizer provides an intuitive interface for tuning and optimizing your Internet connection, but it needs an experienced operator.

SG TCP Optimizer's compact, tabbed interface logically presents all settings and tests. We found SG TCP Optimizer efficient from the moment it quickly opened. The six tabs presented general and advanced settings, a tool to discover your system's largest possible nonfragmented packet, a calculator to figure your RWIN value, a latency test, and a quick Windows Registry editor. If you have no idea what those settings do, this program isn't for you. If you do have some experience, a short tutorial helps you quickly discover and enter the proper Registry settings to improve connection speed.

Settings are easily saved in backup files, making it easy to try different settings and revert if you accidentally slow connection speed. The help file gives basic information, although it's nothing a system administrator doesn't know.

Novices, on the other hand, shouldn't bother with this application. Its many settings, though easily changed, could cause serious system slowdowns if improperly altered. System administrators and advanced users will love this freeware's small size, powerful functions, and helpful tests.
