Having a large (10%) free space threshold allows the file system to
use faster allocation techniques.  From the tunefs(8) man page-

     This value can be set to zero, however up to a factor of three
     in throughput will be lost over the performance obtained at a
     10% threshold. Settings of 5% and less force space optimization
     to always be used which will greatly increase the overhead for
     file writes.
