MySQL Performance Analysis with Percona Toolkit and TCP/IP Network Traffic
by Baron Schwartz, February, 2012
The TCP network traffic conversation between a client and a MySQL server is a rich source of data for many types of analysis. In this paper, we show how the simplest type of traffic packet headers with no payload can provide a surprising variety of information about the system’s performance. The techniques that we demonstrate are quick, require o - Read More

Improving Percona Server performance with Flashcache on the Virident tachIOn Drive
by Baron Schwartz, Vadim Tkachenko, August, 2011
Using flash storage as a second-level cache for MySQL, between disk and main memory, reduces I/O latency while avoiding the size and cost limitations of storing the data on flash alone. This white paper presents the results of our benchmarks with Facebook's Flashcache module and the Virident tachIOn PCI-E storage device. We explain when it is cost- - Read More
Scaling MySQL With Virident Flash Drives and Multiple Instances of Percona Server
by Baron Schwartz, Shridar Subramanian, Vadim Tkachenko, May, 2011
Hardware continues to outpace software, and with the large amounts of memory, many CPU cores, and enormously powerful flash drives readily available today, a hybrid strategy of multiple database servers per physical server is necessary to better utilize the hardware's capacity. Such a configuration can enable a 5x to 15x consolidation factor, and i - Read More
Causes of Downtime in Production MySQL Servers
by Baron Schwartz, March, 2011
Everyone wants to prevent database downtime by being proactive, but are measures such as inspecting logs and analyzing SQL really proactive? Although these are worthwhile, they almost always identify problems that already exist. To be truly proactive, one must prevent problems, which requires studying and understanding the reasons for downtime. T - Read More
Scaling MySQL Deployments With Percona Server and Virident tachIOn Drives
by Baron Schwartz, Shridar Subramanian, Vadim Tkachenko, February, 2011
Until recently, MySQL and InnoDB were unable to take advantage of high-performance hardware, particularly storage systems. Large-scale deployments made heavy use of so-called horizontal scaling with a technique called sharding — partitioning data across many small-to-midsize servers. Today, MySQL — especially Percon - Read More
Preventing MySQL Emergencies
by Baron Schwartz, February, 2011
Preventing downtime-causing emergencies in MySQL can be difficult because they are caused by complex combinations of several things going wrong. Efforts to be proactive may be sincere, but without knowledge of the causes of emergencies, they often fail to prevent further problems. This white paper explains dozens of ways that real emergencies coul - Read More
Configuring Percona Server with XtraDB for Fast Restarts
by Baron Schwartz, Vadim Tkachenko, January, 2011
InnoDB requires a long time to restart on servers with large amounts of memory. It can take many hours to warm InnoDB up enough to serve queries quickly. The database's "working set" of data is not in memory after a restart, so queries must perform random disk I/O to read pages, and are thus too slow for production use. Percona Server with XtraDB g - Read More
Forecasting MySQL Scalability with the Universal Scalability Law
by Baron Schwartz, November, 2010
Forecasting a system's scalability limitations can help answer questions such as “will my server handle ten times the existing load?” and “at what point will I need to upgrade my hardware?” Timely answers to these questions have more business value than exact predictions. Mathematical models can help reduce guesswork while - Read More
