Thanks, those do help a little.  1 more req/s for GetsSets and about 10 
more for the small file read.

The point of that test was to simulate the memcached call using a file 
on disk.  I would never do it that way in the real world.  In PHP I 
would use readfile() to do the job.  Using readfile(), the PHP script 
tests at 100 more req/s.  But, I was trying to create scenarios that 
were as similar as possible to reading the key from memcached.  You 
can't really chunk that unless you break up the cache to start with.
