Hi there. My environment is Ubuntu 12.04. I have been working with it for more than a year. I mostly do numerical simulations. Now I am at the stage where I will need to store some data in a database, simply because they are rather long to compute. I don't anticipate a very large volume. What I need is to get a very fast retrieval. So I installed MySql, community variant, as they say.

(1) Is there any problem with that given the way I work?

Before installing MySql I googled and a Percona website showed up. It offered to configure a file for me: my.cnf. I went for it. Thus the site configured something and I had to register with them. They seem to offer reasonable tune up although there might be hidden threats, I don't know. My second question is:

(2) Is there any problem with it?

(3) My third question is how to use MySql from a fortran program. There is a website that offers an API for this but I don't know if it's good for linux. There might be other similar software.

So, I expect to get some answers, thanks, - A.

Usually there is no need to have some external service to configure my.cnf. Mysql comes with a working setup when you install with apt-get or aptitude.

Hope this helps

I know this website. MySql link is broken there. Thanks.

Percona is legit so there is no 'threats' with using their tool, but it won't be optimal for your setup. You could try http://mysqltuner.com/ which reads your database configuration and stats to give you recommendations. Also you could take a look at Redis.
