Speed inserts and selects

Hi,

I'm moving my database to mysql but there is one table that is pretty big (more than 47 million rows for each year) and it takes years to insert all the data.

I already tried everything I found in the forum, partitioning, index, fulltext...and is true it works better but its far away from efficient.

For giving more background: The data base is about hydrological data recorded during the past ten years. In my data base there are three tables: one keeping the objects to be saved, another to save the sensors of each object and the last one and the one which is causing the big problem is where I keep hourly all the information collected for each sensor (this table will have 47 million data for each year int the database)

Is there any way I can performed the inserts in less than 10 hours?

Thank you very much!
