I have done some research on this and i am able to go up to 4MB/s in data transfer, it is not much but it is a lot for mirc.
There have been many claims that mIRC is slow when it comes to transfers. Given your research is showing some pretty decent (
amazing if you mean MB == MBYTE and not mbit) results, it would be great if you could post a complete article / guide on the methods you're using to get this kind of speed. I think it would be helpful to other scripters who are having these speed complaints.
