I think I can speak for Refractions when I say, do tell!

We're always interested in performance info. If it's slow, then we'll know we 
need to make it faster; if its fast, then that's great. No harm in letting 
everone know which way is fast and which way is slow. There's no license 
attached to postgis disallowing you from publishing performance comparisons 
without our explicit permission (as there is with Oracle...) so go right ahead. 
No place would be better than here on the list.

Please post the hardware you're running the tests on (architecture, processor, 
memory) as well as some idea of the size of the dataset so we have a baseline 
for the performance measurements.

Later,
Chris
