Internet Download Optimizer (IDO) can accelerate your downloads by up to 200% with a new TCP/IP optimization logic. Its wizard determines your operating system and guides you through a number of steps to achieve better Internet performance. IDO currently supports Windows 95/98/ME/NT/2000 operating systems and finds your optimal MTU, MSS, buffer sizes and other settings for a given host automatically.

The distribution package includes one small binary file and a comprehensive help file that describes the wizard and explains the settings it makes in the registry. DialUp, LAN, cable and DSL adapters are supported. This version also has "keep-connection" feature that prevents you from being disconnected by your ISP.

Version 4.1 also includes support for Microsoft Internet Explorer, Outlook, ICQ, Netscape, IRC, MSN, America Online and all FTP clients and download managers. You may register 30-day trial version of Internet Download Optimizer for only $14.95 (special limited time offer).
