AMD EPYC Performance Testing… or Don’t get on the wrong side of SystemD

 | July 11, 2018 |  Posted In: Benchmarks, MySQL, Percona Server for MySQL

Ubuntu 16 AMD EPYC

Ever since AMD released their EPYC CPU for servers I wanted to test it, but I did not have the opportunity until recently, when started offering bare metal servers for a reasonable price. So I started a couple of instances to test Percona Server for MySQL under this CPU. In this benchmark, I discovered some […]

Kubernetes, and its most popular distribution OpenShift, receives a lot of interest as a container orchestration platform. However, databases remain a foreign entity, primarily because of their stateful nature, since container orchestration systems prefer stateless applications. That said, there has been good progress in support for StatefulSet applications and persistent storage, to the extent that it […]

How Binary Logs (and Filesystems) Affect MySQL Performance

 | May 4, 2018 |  Posted In: Benchmarks, InnoDB, Insight for DBAs, MySQL, MySQL 8.0

I want to take a closer look at MySQL performance with binary logs enabled on different filesystems, especially as MySQL 8.0 comes with binary logs enabled by default. As part of my benchmarks of the MyRocks storage engine, I’ve noticed an unusual variance in throughput for the InnoDB storage engine, even though we spent a […]

Sysbench-tpcc Supports PostgreSQL (No, Really This Time)

 | April 19, 2018 |  Posted In: Benchmarks, Database Monitoring, Insight for DBAs, MySQL

Sysbench-tpcc Supports PostgreSQL

This time, we really mean it when we say sysbench-tpcc supports PostgreSQL. When I initially announced sysbench-tpcc, I mentioned it potentially could run against PostgreSQL, but it was more like wishful thinking than reality. The reality was that even though both databases speak SQL, the difference in dialects was too big and the queries written […]

In this blog post, we look at the performance of Percona XtraDB Cluster on Amazon GP2 volumes. In our overview blog post on Best Practices for Percona XtraDB Cluster on AWS, GP2 volumes did not show good results. However, we allocated only the size needed to fit the database (200GB volumes). Percona XtraDB Cluster did not show […]
