I am having trouble maintaining a decently steady speed while sending files. I have my max cps set at 33000. The speed changes constantly from 33K to 1K to 15.4K to 520 bytes to 35K and so on. I have tested my upload speed with FTP and Bit Torrent transfers and my upstream speed is solid. I only have problems with mIRC. Anybody know what might be going on?

- I am behind a firewall although I do not have it configured through mIRC.
- I am running a WinXP machine and using mIRC version 6.16
