Query Caching or NOT?!!!

mysql is already very very fast in getting results when you use normal queries.
Queries that only have one table and use indexed keys to get result. Caching will only start making a visible effect when used on joined tables and when this query is trigger numerous times per page view.

I dont think on a simple post page you will much any visible speed improvement when you use query cache.

Personally I think its far better to optimize your data structure and use indexed field correctly.

On the package it said needs Windows 7 or better. So I installed Linux.
