Yonik Seeley commented on LUCENE-2378:
--------------------------------------

A little more info on this.  I originally thought that it was going to be a MultiFields issue
only... but I stuck in an optimize and the performance on 3x is still much better.

Single segment performance:
trunk bulk read: 1823ms
trunk nextDoc: 1473ms
branch_3x bulk read:647ms

> A number of places still use the pre-flex APIs.
> This is actually healthy, since it gives us ongoing testing of the back compat emulation
layer.
> But we should at some point cut them all over to flex.  Latest we can do this is 4.0,
but I'm not sure we should do them all for 3.1... still marking this as 3.1 to "remind us"
:)
