I am using mIRC as an remote application on my server (I am the only user), but when I am connecting to a server with mIRC, or joining a new channel, mIRC keeps hanging for about 2 to 3 mins. Now with initial connecting it is not a big problem, but if you need to fast join a channel or sort, it is rather anoying.

Also when A server disconnects and reconnects while I am "restart" the application (re-connecting to the application), it completly hangs and I need to forcefully logoff the complete session, since even killing the process does not work.
CPU: 4 cores 2,6 Ghz
