[mohaa] Getting Complanes About High Ping, Is Config Ok?

[Roger Lund]

it is a 1.7 p 4 with 512 of sdram and a 60 gig5400 rpm hd. nothing else is
running much. tryed with anohter box with the same cfg file and same
thing. speed tests all give 1.5 up and down. the connection is a business
cable connection 1.5 both ways. They call it a T1 connection.
