LiveCode and SQLite performace

[Richard Gaskin]

The guidelines I'd read were about 15% IIRC;  I believe there used to be 
a tech note on this, but I can no longer find it at apple.com.  Most 
third-party sites discussing this cite 15%.

If OS X required us to never use half of our disk space that would be 
quite a public controversy, since that's far beyond what any other file 
system requires and would represent a tremendous waste of storage resources.

If you have poor performance on a Mac that has more than 15% free, 
chances are free space isn't the cause.

There may be other issues with the drive (+1 for Disk Warrior), or 
either the primary or a secondary drive has a power-scaling feature that 
lets the platter rest when not in use, or corrupted b-tree elements, or 
any number of other factors.
