Just I've recently seen claims at 1-3" penis enlargement in my mailbox. So I know how tempting such bullish claims can be! 3" sounds like a lot, I guess, but as a percentage its not such a big deal, so I am passing on this stuff for now... > Can we boost Internet connection speed in Linux? If the answer is "yes", > then how? Thanks for the help. Windows users are assumed to be hung up on dialup, and thus Uncle Bill sets them up that way. Linux is more set up for macho LAN type speeds, so the typical MS weenie-shortcomings don't exist. The only likely benefit you'll get is if you have a highbandwidth connection with typically high latency round-trips (such as Orient -> USA). Then you can adjust the TCP receive window upwards and see if that helps. For most of us, there is no need. -- Hal Burgiss -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://www.redhat.com/mailman/listinfo/redhat-list
