I recently downloaded the free version of Limewire and not the Pro (purchase) and I just noticed that my download speed is capped at 10k/sec?

I've seen all the guides and problem solving options you all have posted to speed up / freeing up ports / etc.

A few days ago limewire was flying at 100-400k/sec downloads.

Is this because the freeware is speed capped or am I missing something?

Does Pro make a difference? Any input will be greatly appreciated. (Just don't post any more suggestions if its my firewall,etc, my ISP does not filter btw)

Just a simple question if Pro and Freeware speed difference.

Thanks.
