1. If its the same machine then you get only a slight performance improvement.
2. Yes INDEXes or KEYs are available in mysql for Win32, UNIX, Solaris, Linux...
Using INDEXes will speed up your query.
There are also multiple column INDEXes.
You can create up to 16 KEYs per table with each KEY up to 15 columns in it and up to
256Bytes per KEY.
To eliminate duplicates you have to use an UNIQUE or PRIMARY KEY.
You obviously didn't RTFM ( Read The Full Manual :)
