whenever i enter a command there is always a few seconds pause before anything happened is that just mud lag?
also i would like to know some tips to make anything shave a few secondsoff here and there, i want to be as fast as possible
Unless you have set up some very unusual alias that somehow waits and then sends the command, then yes, it is mud lag.
You can test this by connecting with another client (eg. telnet that comes with every copy of Windows). You should see the same lag.
MUSHclient is a very fast client, I doubt you can do much to speed it up at the client end. The only thing that might slow it down is a trigger matching on multiple asterisks, eg.
Match on: **** shutting down ****
Because * is a wildcard, MUSHclient gets confused if you have multiple ones in a row.
Make sure you don't have any such triggers. If you need one, make it a regular expression, like this:
Match on: \*\*\*\* shutting down \*\*\*\*
That way it just looks for asterisks, not wildcards.
