PgBouncer defines one pool per user+database combination. A client benefits from a pooled connection only if it connects to a child which has previously served a connection for this database+user combination. PgBouncer allows limiting connections per-pool, per-database, per-user or per-client. Performance Testing.

This post complements the previous best practice guides this time with the focus on MySQL and MariaDB and achieving top levels of performance with the HammerDB MySQL TPC-C test. Similarly for this guide MySQL can be swapped for a mySQL based databases such as MariaDB. SELECT DISTINCT c from sbtest where id between ?

We perform testing from the starting of the flow till the end of the flow. Functional Testing can be easily automated once the features being tested are stable and are not expected to go through a lot of new changes. Performance Testing. Different types of performance tests are-.

I was mostly coding in C, tuning FORTRAN, and when I needed to do a lot of data analysis of benchmark results used the S-PLUS statistics language, that is the predecessor to R. We had specializations in hardware, operating systems, databases, graphics, etc. It was the first database sizing guide Sun had ever produced.

On Mabl, tests can be run on emulators; it also has a feature that mimics desktops or mobile devices, and you’ve got the flexibility to choose screen orientation and devices (for instance, OnePlus 7, iPhone 12, etc.) that you’d like to perform tests on. Picture credit: Mabl. It supports CI/CD tools.

Plotting the percent performance loss vs syscall rate per CPU, for my microbenchmark: Applications that have high syscall rates include proxies, databases, and others that do lots of tiny I/O. Also microbenchmarks, which often stress-test the system, will suffer the largest losses. Hit Ctrl-C to end. Linux 4.14.12-virtual
