I enjoy hearing about folks heating up multiple cores on their big iron. Reporting from the other end of the spectrum, I have PostgreSQL 9.1 / PostGIS 2.0 running on a Raspberry Pi. My Raspberry Pi’s day job is as a chickencam (that’s a web cam in the hen house monitoring chickens).
I did an intersection of 5k complex polygons in a couple seconds. If the chickens hadn’t been flapping around it probably would have been even faster.
PostgreSQL and PostGIS are amazingly flexible, scaleable pieces of software!
