<h1>Exp Series Performance Tests</h1>
|
|
x-axis is power of 2, log base 2 of size<br/>
|
|
y-axis is "document" operations per second, ex., total document insertions per second<br/>
|
|
<br/>
|
|
For measuring Ruby driver performance, we are interested primarily in the "user" CPU time.<br/>
|
|
The "user" time is the time used by the Ruby driver, typically much less than real time.<br/>
