CPU governor performance

CPU governor performance

In this blog, we’ll examine how CPU governor performance affects MySQL. It’s been a while since we looked into CPU governors and with the new Intel CPUs and new Linux distros, I wanted to check how CPU governors affect MySQL performance. Before jumping to results, let’s review what drivers manage CPU frequency. Traditionally, the default driver […]

Database Compression Methods

This blog post is an update to our last post discussing database compression methods, and how they stack up against each other.  When Vadim and I wrote about Evaluating Database Compression Methods last month, we claimed that evaluating database compression algorithms was easy these days because there are ready-to-use benchmark suites such as lzbench. As […]

Downloading MariaDB MaxScale binaries

In this blog post we’ll discuss a caveat when downloading MariaDB MaxScale binaries. Following the previous performance results in my last two posts on sysbench and primary keys (https://www.percona.com/blog/2016/04/07/mysql-5-7-sysbench-oltp-read-results-really-faster/ and https://www.percona.com/blog/2016/03/28/mysql-5-7-primary-key-lookup-results-is-it-really-faster/), I wanted to measure overhead from proxies servers like ProxySQL and MaxScale. Unfortunately, I found that MaxScale binaries are not available without registering on the […]

MySQL 5.7 sysbench OLTP read-only results: is MySQL 5.7 really faster?

 | April 7, 2016 |  Posted In: MySQL

MySQL Document Store

This blog will look at MySQL 5.7 sysbench OLTP read-only results to determine if they are faster than previous versions. As promised in my previous post, I have checked MySQL 5.7 performance against previous versions in a different workload. This time, I will use sysbench OLTP read-only transactions (read-write transactions are part of future research, […]

MySQL 5.7 primary key lookup results: is it really faster?

 | March 28, 2016 |  Posted In: MySQL

database support

This blog examines MySQL 5.7’s primary key lookup results, and determines if MySQL 5.7 is really faster than its early versions. MySQL 5.7 was released some time ago, and now that the dust has settled it’s a good time to review its performance improvements. I’m not doing this just to satisfy my own curiosity! Many […]

Percona Server 5.7 performance improvements

In this blog post, we’ll be discussing Percona Server 5.7 performance improvements. Starting from the Percona Server 5.6 release, we’ve introduced several significant changes that help address performance problems for highly-concurrent I/O-bound workloads. Some of our research and improvements were re-implemented for MySQL 5.7 – one of the best MySQL releases. But even though MySQL 5.7 […]

Percona XtraDB Cluster in a high latency network environment

 | March 14, 2016 |  Posted In: MySQL

high latency network enviroment

In this blog, we’ll discuss how Percona XtraDB Cluster handled a high latency network environment. Recently I was working in an environment where Percona XtraDB Cluster was running over a 10GB network, but one of the nodes was located in a distant location and the ping time was higher than what you would typically expect. For […]

Measuring Docker IO overhead

Docker

This will be another post on using Percona Server via a Docker image. I want to follow up on my previous post regarding CPU/Network overhead in Docker “Measuring Percona Server Docker CPU/network overhead” by measuring  if there is any docker IO overhead on operations. After running several tests, it appears (spoiler alert) that there is no Docker IO overhead. […]

Measuring Percona Server Docker CPU/network overhead

 | February 5, 2016 |  Posted In: MySQL, Percona Server

Docker

Now that we have our Percona Server Docker images, I wanted to measure the performance overhead when we run the database in the container. Since Docker promises to use a lightweight container, in theory there should be very light overhead. We need to verify that claim, however. In this post I will show the numbers for CPU and network intensive workloads, […]
