I do see huge SQL commands on this list sometimes: great big commands of 
hundreds of characters which could be done simpler and faster if split into two 
small SQL commands.

Solid State Drives.  Those things of Flash memory you can use instead of a 
rotating hard disk drive.  They're getting very cheap.

A lot of the time taken for hard disk access is spent waiting for the disk to 
rotate to the right place so the read/write heads can get at the sector you 
want.  SSDs never have to wait.
