So, we pitted the two connection poolers head-to-head, using the standard pgbench tool, to see which one provides better transactions per second throughput through a benchmark test. For good measure, we ran the same tests without a connection pooler too. Testing Conditions. Final Words.

These development and testing practices ensure the performance of critical applications and resources to deliver loyalty-building user experiences. Because pre-production environments are used for testing before an application is released to end users, teams have no access to real-user data. What is synthetic monitoring?

The patches that workaround Meltdown introduce the largest kernel performance regressions I've ever seen. Many thanks to the engineers working hard to develop workarounds to these processor bugs. Much of my testing was on Linux 4.14.11 These results aren't final, since more changes are still being developed, such as for Spectre.
