Hi crs, what speed is the processor in your machine (and what type etc.), as 
my previous email showed, my old Athlon 2GHz (single core), with the 
database running on a single SATA hard disk, could do ~15000 rows in ~14-15 
sec, around 1000 rows a second, your data points are ~3000 rows in 30 sec, 
around 100 rows a second. We should try and determine what could make your 
database run at only 10% of the speed before throwing away rows.
What was the OS, and did the mysql come as a pre-compiled package (I have 
had issues with mysql before when compiled from source).
