iSpeed for Windows Version 3.18 Copyright c 1997-2002, High Mountain Software web site: www.hms.com email: support@hms.com voice: 720-904-8199 (support callbacks unavailable) fax: 419-715-2941 Requirements: - Windows 95, 98, ME, NT 4.0 SP4+, 2000 and XP - TCP/IP Networking installed and bound to one or more network adapters - Windows Sockets 2.0 (included with all but Win95) - Desire to maximize your network performance iSpeed is a utility that will help to optimize your networking connections - both ethernet and modem (dialup networking). It does this by manipulating the Maximum Transmission Unit (MTU), Maximum Segment Size (MSS), Receive Window (RWIN), Time To Live (TTL), MTU Auto Discover, Black Hole detection and NDI Cachesize. These items are relatively undocumented by Microsoft, and fine tuning them can have a dramatic effect on your throughput (both positive and negative). Use this program at your own risk! High Mountain Software will NOT be liable for any damage done. That said, this program is safe to use and you can easily reset everything to the defaults as provided by Microsoft. Note too, that anytime you make changes to the registry, you run the risk of making your system unbootable. It is always wise to make sure your Emergency Recovery Disk is up to date, and to backup your registry files before making any changes to your registry. Please see your system documentation for information regarding the making of an emergency disk and backing up your registry files. Please email your comments and suggestions to support@hms.com. You can always find the latest version of this and other High Moutain Software applications on our web site at http://www.hms.com. Enjoy!
