Scaling PostgreSQL on SMP Architectures -- An Update

Updates last year's 10th Anniversary Summit presentation on Unisys efforts to enhance scalability of PostgreSQL on 32-bit and 64-bit shared multiprocessor Linux platforms. Measurements reflecting improvements in newer PostgreSQL releases are summarized and possible strategies for further improvement are discussed.

Unisys is positioning PostgreSQL as a data engine of choice for open source Java Enterprise Edition software stacks on high processor count, Linux-based 32-bit and 64-bit SMP hardware platforms. Characterization and enhancement of PostgreSQL's performance and scalability on these high-end systems is of paramount interest. The talk will summarize the current state of continuing efforts begun in 2005 to characterize PostgreSQL's capabilities on 8-cpu and higher systems and updates results, originally presented at the 2006 10th Anniversary Summit, for more recent releases of PostgreSQL. Possible strategies for further improvement, based on analyses of current bottlenecks on SMP systems, will be described in some detail.
