As our Percona Kubernetes Operator for Percona XtraDB Cluster gains in popularity, I am getting questions about its performance and how to measure it properly. Sysbench is the most popular tool for database performance evaluation, so let’s review how we can use it...

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....

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....

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...

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...

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...

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...

IMPORTANT: DON’T TRY THIS IN PRODUCTION. As demonstrated by Marko (see comments), it may corrupt your data. In a post, written a few months ago, I found that using EXT4 transactions with the “data=journal” mount option, improves the write performance...

An idea for a benchmark based on the “arrival request” rate that I wrote about in a post headlined “Introducing new type of benchmark” back in 2012 was implemented in Sysbench. However, Sysbench provides only a simple workload, so to be able to...

A few years back Deva wrote about how to use tcpdump on very busy hosts. That post sparked my interest about exploring how to measure the impact of tcpdump on very busy hosts. In this post, I wanted to highlight how much of an impact there really is and what options...

In this blog post, we will discuss MySQL performance on eXFlash DIMMs. Earlier we measured the IO performance of these storage devices with sysbench fileio. Environment The benchmarking environment was the same as the one we did sysbench fileio in. CPU: 2x Intel Xeon...

A few days ago I wrote about MySQL performance implications of InnoDB isolation modes and I touched briefly upon the bizarre performance regression I found with InnoDB handling a large amount of versions for a single row. Today I wanted to look a bit deeper into the...

Monitoring flow control in a Galera cluster is very important. If you do not, you will not understand why writes may sometimes be stalled. Percona XtraDB Cluster 5.6 provides 2 status variables for such monitoring: wsrep_flow_control_paused and...
