EDIT: Adding some more detail here. I'm specifically looking for help performance tuning SQL Server stored procedures.
I don't know why this was tagged with MySQL, I removed that. I'm working with TSQL sprocs on SQL Server 2014.
Could you add a bit more detail to your question? There are many aspects of performance tuning a server. You can tune MySQL config, the server itself, sql queries, etc... Is your database an instance on something like Rackspace Cloud Databases or AWS RDS? Or is it MySQL installed on a Linux server? Windows server? Are you accessing the database locally or from another server?
All of these questions come in to play when performance tuning MySQL.

looks like a good place to start.
There is a person who gives a free online tutorial, here is its email Id learnittools@gmail.comask him about upcoming batches. he teaches very nicely and also gives the assignments in each class that you have to submit. and if you don't want to spend one month the w3school is the best place to learn quickly.
