Good to hear, Larry - thanks for testing this.

Congratulations Martin! Buffering 41 complex aircraft features took
83 seconds with your old algorithm, and only 2 seconds using your new
one. I could find no anomalies.

JTS'ers,
As you may have experienced, buffering in JTS currently has some
performance challenges in situations involving large buffer
distances. I'm excited to say that I've implemented some code
enhancements which *dramatically* improve buffer performance in
these cases (as well as providing an overall improvement).
I've tested this code as extensively as I can, and am pretty
confident that it is robust and accurate. But it's always good to
have other people beat on it as well!
So, is anyone out there ready, able and willing to test out the
new buffering code? Ideally this would be someone who has a
application which uses buffering in a significant way, and which
allows determining the performance and correctness characteristics
effectively. I'm looking for feedback to either confirm that this
really is an improvement, or some test cases which reveal issues
if there are any.
If you're able to help out, you can either download and build the
codebase from CVS, or I've built an alpha release of JTS 1.10
which is available here:

Thanks - Martin
