This has been suggested in the past (don't have the link at the moment, but you can search for it). mIRC will probably, in the future, move to 64-bit. However, right now, there is no performance benefit to having mIRC compiled in a 64-bit application. The simple reason is that 64-bit compiled applications will only see a relative performance boost when they deal with large quantities of data. mIRC, as far as IRC clients go, doesn't deal with nearly enough data, no matter how much you are throwing at it, to warrant the need for it to be compiled 64-bit. In fact, I'm pretty sure that mIRC's performance as a 32-bit application is better than if it were to migrate to 64-bit (mIRC performs small cache/buffer operations, and the limits that are inherent in an IRC client and server).
All in all, don't expect mIRC to be 64-bit anytime soon. I hope this helps!
