I'm having a little difficulty understanding your post completely.
First, the pings you're describing are all fine. There's a difference between the ping shown in the F1 screen and the one in the F6 screen, so what you are seeing is normal and nothing to worry about.

Although there is a direct correspondance, remember that they are different.
Now for suggestions...
Try ending the servers that are working well to see if the remaining one, that was slow, suddenly improves.
That will tell us which way to go.
Also, you know it is not necessary to have 3 completely separate installations of UT patched to 451 to run 3 servers at once?
[list:73de907dd9]It is only necessary to have 3 different sets of INI and LOG files.[/list:u:73de907dd9]
You didn't mention what OS you were using. Knowing it will help us, help you.
Does this make sense? Hope it helps.
