Question

I am working on a game that I am going to open to the public to have on their game.
The game stores lots of information (about 300 rows) per website and spends a lot of time updating values within this MySQL database.

Is it better (faster/efficient) to add a new table for every website or to just have 1000’s of rows in one table and add a column “website_id” or similar?

Answer 1

It is better to add more rows in the same table and create an index on the table. An index on the website_id would probably help a lot.
