Postgres Performance - Default Pgbench configurations

Continuing the PostgreSQL Performance series:

Please read more about Test Particulars / Chart Naming methodology from the previous post in the series.

Takeaway:
  • Unrelated to the Read-Only performance mentioned earlier, which grew slowly over each Major release, these numbers have grown considerably specifically in 9.5
  • 9.5 Branch is at times 35-70% faster than 9.4 Branch
  • To reiterate, this test had no Pgbench flags enabled (no Prepared / no Read-Only / etc.) besides 4 Connections & 4 Threads.

Wow, I didn't expect such a big improvement in 9.5. I knew we made some improvements, but didn't expect it to show that clearly.
