> I want to see the performance differences (with various read, write
> ratios) between a pure query cache implementation and a modified query
> cache implementation. The intended modification is to allow the query
> cache to cache the queries after parsing (now it just caches the query
> before doing a processing) but what I wanted to see is how it behaves
> if we parse and store the query (then semantically identical queries
> will be identified as identical which is not the case now).

> start to my work?
> It'll be great if anybody can give some feedback on this about where
