Description

I'm proposing that we change the default behavior for the DataCache. Currently, the DataCache is turned off by default. Our competition is turning on their L2 cache by default. Thus, out-of-the-box comparisons are killing us. We have to explain the difference, get them to change the configuration one way or the other for apples-to-apples comparisons, and then re-run the benchmark. By that time, it's too late. We already lost.

Due to the upcoming 2.0.0 release, it seems like a good time to change this default. Please comment directly to this JIRA.

Thanks,
Kevin
