Sysbench has long been established as the de facto standard when it comes to benchmarking MySQL performance. Percona relies on it daily, and even Oracle uses it when blogging about new features in MySQL 8. Sysbench comes with several pre-defined benchmarking tests. These tests are written in an easy-to-understand scripting language called Lua. Some […]Read more
Percona has a long tradition of performance investigation and benchmarking. Peter Zaitsev, CEO and Vadim Tkachenko, CTO, led their crew into a series of experiments with MySQL in this space. The discussion that always follows on the results achieved is well known and praised even by the PostgreSQL community. So when Avi joined the […]Read more

In this blog post, I will demonstrate how to run and use sysbench histograms.
One of the features of sysbench that I often I see overlooked (and rarely used) is its ability to produce detailed query response time histograms in addition to computing percentile numbers. Looking at histograms together with throughput or latency over time […]
In this blog post, we’ll look at Performance Schema benchmarks for OLTP Read/Write workloads.
I am in love with Performance Schema and talk a lot about it. Performance Schema is a revolutionary MySQL troubleshooting instrument, but earlier versions had performance issues. Many of these issues are fixed now, and the default options work quickly and […]
This blog compares how PostgreSQL and MySQL handle millions of queries per second.
Anastasia: Can open source databases cope with millions of queries per second? Many open source advocates would answer “yes.” However, assertions aren’t enough for well-grounded proof. That’s why in this blog post, we share the benchmark testing results from Alexander Korotkov (CEO of […]
In this blog post, we’ll discuss how to benchmark MongoDB with sysbench.
In an earlier post, I mentioned our use of sysbench-mongodb (via this fork) to run benchmarks of MongoDB servers. I now want to share our work extending sysbench to make it work with MongoDB.
If you’re not familiar with sysbench, it’s a great project developed by Alexey […]
During the last couple of months I have been involved in an unusually high amount of performance audits for e-commerce applications running with Magento. And although the systems were quite different, they also had one thing in common: the MySQL query cache was very useful. That was counter-intuitive for me as I’ve always expected […]Read more
Last week I hosted a webinar on using MySQL in the cloud for High Availability (HA) alongside 451 Research analyst Jason Stamper. You can watch the recording and also download the slides (free) here. Just click the “Register” button at the end of that page.
We had several excellent questions and we didn’t have time […]
