The official TPC-C test has a fixed number of users per warehouse and uses keying and thinking time so that the workload generated by each user is not intensive. By default each virtual user has the concept of a home warehouses where approximately 75% of its workload will take place.

adds full support for MariaDB in both the GUI as shown: And in the CLI as a separate database from MySQL, this post describes a setup and test for MariaDB using the CLI on Linux as an example running the TPROC-C workload. A future blog post on performance profiles will explain why this is a good first test on which to baseline other changes).

In this example, we will run a PostgreSQL TPROC-C autopilot workload to generate some jobs to analyse.

more capable, and built from the ground up for the modern era of the eBPF virtual machine. eBPF was created by Alexei Starovoitov while at PLUMgrid (he's now at Facebook) as a generic in-kernel virtual machine, with software defined networks as the primary use case. It's shaping up to be a DTrace version 2.0: Attaching 2 probes. ^C

bpftrace is a new open source tracer for Linux for analyzing production performance problems and troubleshooting software. Linux already has many performance tools, but these are often counter-based and have limited visibility. Originally posted at https:/opensource.com/article/19/8/introduction-bpftrace.
