As a note, some ISPs limit DCC send speeds. You can send faster on other protocols, but the DCC speed is limited due to it being used by so many people to send illegal files. Beyond this, ISPs can even block sends and/or downloads of specific file types if they choose to (such as .mp3), though that's most common in universities and not with your normal ISP.
Edit: Btw, you probably know what you are meaning by your speeds, but just to make sure... Is 250k your typical send speed to someone using another program, or is that what your ISP tells you that your upload speed is? 250kbit upload speed (probably 256kbit) would really be a speed of around 25-30kB/s actual speed.
