When I checkout Subversion trunk from my local mirror I cannot measure a
client gain, but I can measure better server efficiency:

 - The CPU used by Apache goes down from 1.2s to 1.1s.

 - The number of system calls made by Apache goes down

      68822 to 50664 for hot FSFS cache
     178885 to 161722 for cold FSFS cache
