Hmmm.

Because your question has been answered many times before, and you are expected to read the rules and search the forums first before asking the same question.

Also, it's a very difficult question to troubleshoot, since the reasons for slow downloads being slow are usually not because of the LimeWire software.

If you want a decent test of download speeds, try one of the files from a reliable server, like those listed on http://www.magnetmix.com/audio2.shtml (they are free and authorized for sharing, and can usually hit speeds > 100 KB/s).
