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.
