The PostgreSQL Global Development Group has announced the PostgreSQL 9.2 open source database with native JSON support, covering indexes, replication and performance improvements.

But what does “performance improvement” really mean with this kind of technology?
Vendors of all kinds love to use the term “performance” time and time again, so what makes an open source next-generation database operate and, well, perform, so well in this case?
How it works…
The answer appears to lie in PostgreSQL 9.2’s ability to execute “linear scalability” across 64 processor cores to share out the burden of processing. This separation of workloads… plus its ‘index-only’ scans and reductions in CPU power consumption are what actually speed up this product.
NASA, Instagram and HP can’t be wrong? Can they?
Organisations including the U.S. Federal Aviation Administration, Instagram and NASA run applications on PostgreSQL and HP has adopted it too to power its HP-UX/Itanium solutions.
Improvements in vertical scalability are also said to increase PostgreSQL’s ability to efficiently utilise hardware resources on larger servers.
So just how fast is fast here?
Numerically, this means:
* Up to 350,000 read queries per second
* Index-only scans for data warehousing queries
* Up to 14,000 data writes per second
NOTE: PostgreSQL is an open source object-relational database system. It has more than 15 years of active development and runs on all major operating systems, including Linux, UNIX (AIX, BSD, HP-UX, SGI IRIX, Mac OS X, Solaris, Tru64) and Windows.
