Will Tomato work with existing guides on this forum?

For example:
Samba
Rtorrent
Vsftp
Cron
etc.

What about perfomance? On my WL500 G Deluxe i have speed issues due the the low CPU performance. Will this be slightly increased with Tomato?

I'll will only change to Tomato if I have the same stability, features and hopefully a better CPU performance on Torrent files, and FTP transfers.
