Re: mysql is really a slow rdbms
It is not that mysql it slow, its your database design and the fact you have 2.5 million records in the table. It is not clear from your description of the problem what you are trying to do, so giving advice is that much harder. If you are creating an index on the column hari, it will take a long time. However this time is negligable because you only do it once, and never again. But if you are talking about a query that uses the column hari going slow, making it a key in the table will speed up your query considerably. Hope this helps.

Re: mysql is really a slow rdbms
Just simple question.. why u designed it such a way that differentiate the 'thn','bln' and 'hari' field when you can do it just using one field and using DATE type field instead of integer. and when you query u can use your SQL sorting to speed up searching.
