[postgis-users] Throughput/performance for postGIS

[Gregory S. Williamson]

I would think so, too. Still, some idea of how people have done with somewhat smaller loads might help us.

Informix charges a few tens-of-thousands of dollars for a runtime license ... we can throw a lot of hardware at the issue (getting cheaper all the time), and our engineering staff tells me they are confident about being able to pool many database servers. And if we add some code/testing to postgres/GIS, so much the better.

Of course, it figures that we've just gotten most of our Informix issues squared away so we'll be changing now.

Well, something new to learn, at least !

Thanks for your participation in the users' groups.

I will be interested in hearing what others say, but my guess would be 
that GX would be the most heavily scaled PostGIS implementation in the 
world.

We have found Solaris to be slower than Linux general, and others have 
found Windows slower than Linux, but that is the extent of OS experience 
I haev heard. I would be interested to know if FreeBSD has any 
performance advantages over Linux for PostGIS apps.
