Dear Sirs,

There is a suggestion to implement performance tests and benchmark pgSphere. One of the important pgSphere features is the fast access and search to spherical objects using indexes. To improve existing functionality, we need a way to identify bottlenecks and compare modification results. We should benefit from performance testing.

There are some but not all the questions related to performance testing:
- Which data patterns to use?
- Where to get test data?
- How to configure PostgreSQL?

I would like to start discussion of the pgSphere performance testing. I welcome any feedback and suggestions on the subject.
