Turns out the 40% was due to a configuration problem with my application. I'm now getting the same performance with
communityedition. 

It appears that I'm now CPU bound. My CPU's are all pegged.

Yes. I didn't know the proper vernacular :-)

It is very likely that the default settings are different. I'm looking at that right now.

What exactly is "the enterprisedb distribution"?
Are you talking about the the Advanced Server?

I would be very surprised if the code base would differ so much to allow such a performance gain.
Could it be that the default settings for the Advanced Server are different than those of the "community edition"?

And what did you have installed before that? (as the Windows binary are always distributed by EnterpriseDB)
