performance tests

Hi everyone,

I need to try different types of engines for a MySQL database that will be created by a program in C++. The program has to create the database and populate it. I need to measure times and sizes for the database to find which gives the better overall performance. Right now, I am measuring time with a timer class for measuring time to populate the database. I want to know if someone knows if MySQL itself provides a way to determine the size of a database, and perhaps also ask on what things to consider for these performance tests.

Thanks in advance,


Check information_schema database (if you are using MySQL 5.0)
