Exp Series Performance Tests

x-axis is power of 2, log base 2 of size
y-axis is "document" operations per second, ex., total document insertions per second

For measuring Ruby driver performance, we are interested primarily in the "user" CPU time.
The "user" time is the time used by the Ruby driver, typically much less than real time.
