Welcome to the third – and last – part of this blog series, exploring how the PostgreSQL performance evolved over the years. The first part looked at OLTP workloads, represented by pgbench tests. The second part looked at analytical / BI queries, using a subset of the traditional TPC-H benchmark (essentially a portion of the […]

TPC-H performance since PostgreSQL 8.3

In the first part of this blog series, I’ve presented a couple of benchmark results showing how PostgreSQL OLTP performance changed since 8.3, released in 2008. In this part I plan to do the same thing but for analytical / BI queries, processing large amounts of data. There’s a number of industry benchmarks for testing […]

OLTP performance since PostgreSQL 8.3

A couple years ago (at the pgconf.eu 2014 in Madrid) I presented a talk called “Performance Archaeology” which showed how performance changed in recent PostgreSQL releases. I did that talk as I think the long-term view is interesting and may give us insights that may be very valuable. For people who actually work on PostgreSQL […]

Last year I wrote about a benchmark which I performed on the Parallel Aggregate feature that I worked on for PostgreSQL 9.6. I was pretty excited to see this code finally ship in September last year, however something stood out on the release announcement that I didn’t quite understand: Scale Up with Parallel Query Version 9.6 […]
