> In the attached test, I fill up the JDBC Channel and then drain it. It appears as the number of the events in the channel, the length it takes to drain the queue increases in a non-linear fashion.
> Events 5,000
> Put  2907 ms
> Take 33615 ms
> Events 10,000
> Put  4469 ms
> Take 259937 ms
> Events: 15,000
> Put  6590 ms
> Take 643294 ms
