Your answers make perfect sense gentlemen - thanks very much.

I just had this idea that, a smaller database with fewer records will
perform better then a bigger one, so by splinting the content of each site
into it's on database, but the same MySQL server, would be better. But
seems I was wrong.

Kindly,
