Installed and seems to work. Tho weighting seems to be quite a bit off (haven't looked at that portion of code yet).

Quick glance at DB shows no reason why it should be slow, if queries match. So those who are having speed issues probably have bad MySQL config just. MySQL scales really efficiently and i don't see immediate reasons why this would be slow, but have to wait for data set to increase.

If anyone got say 8G+ dataset they don't mind sharing, i would be willing to look into it. Or any size with which someone is having some serious perf issues.

Code should be PLENTY more commented btw
