I've seen this on two FreeBSD 4.7 systems connected via a KVM (sharing with two Windows 2003 servers)... typing at the console of them was almost like typing via ssh on a satellite connection. Connecting via ssh was fine, it was only locally that it was a problem. Resetting the keyboard repeat rate on BSD had no discernible impact. I put it down to some sort of interaction between the KVM, the Windows servers and FreeBSD and put up with it... Cheers Antonyhome | help
