Postgres Performance - New Connections

Last in the the PostgreSQL Performance series:

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

Takeaway:
  • New Connection performance has been constant (and at times have mildly deteriorated)
    • i.e. Pgbench with -C
  • I tried to use all possible combinations to find whether a corner case got better over the releases, but almost every test gave the same result.
  • Possibly Tom and others don't consider this a practical use-case and therefore a non-priority.
  • Unrelated, in the future, I'd club / write about such tests in a better fashion, rather than posting them as separate posts. I guess I got carried away by the results! Apologies about that.
