performance boost for SSD

In this blog post, we’ll discuss how a small innodb_page_size can create a performance boost for SSD. In my previous post Testing Samsung storage in tpcc-mysql benchmark of Percona Server I compared different Samsung devices. Most solid state drives (SSDs) use 4KiB as an internal page size, and the InnoDB default page size is 16KiB. I wondered […]

 | August 9, 2016 |  Posted In: Benchmarks, MySQL

In this blog post, I’ll discuss changes I’ve made to the tpcc-mysql benchmark tool. These changes make it less random and support multi-schema.

MySQL Group Replication

In this post, I’ll review Docker multi-host network performance. In a past post, I tested Docker network. The MySQL Server team provided their own results, which are in line with my observations. For this set of tests, I wanted to focus more on Docker networking using multiple hosts. Mostly because when we set up a high availability […]

The need for parallel crash recovery in MySQL

 | June 27, 2016 |  Posted In: MySQL

parallel crash recovery in MySQL

In this blog, I will discuss how parallel crash recovery in MySQL benefits several processes. I recently filed an Oracle feature request to make crash recovery faster by running in multiple threads. This might not seem very important, because MySQL does not crash that often. When it does crash, however, crash recovery can take 45 […]
