Well ive got a big SPEED problem

I'm downloading from the same torrent in the SCTCS and in uTorrent in my PC.

In the SCTCS - Downloaded - 8.00 MiB (1.1%)
uTorrent - Downloaded - 136 MiB (19,5%)

I started at the same time, but the SCTCS is so SLOWWWW
Put also another files to download, but still very slow

I only have the original 30MB of memory (didnt do the upgrade )

Any ideas ?

And how do i install a new version of Enhanced-Torrent ?

Thanks to all
