Virident FlashMAX MLC in tpcc-mysql workload

As I mentioned in previous post on Virident FlashMAX MLC, beside sysbench benchmark, I also run tpcc-mysql (to compare performance Virident FlashMAX vs Fusion-io ioDrive Duo) The report with results is there: http://www.percona.com/files/white-papers/virident-mlc-tpcc.pdf

Clustrix benchmarks under tpcc-mysql workload

I’ve been working with Clustrix team for long time on the evaluation of Clustrix product, and this is the report on performance characteristics of Clustrix under tpcc-mysql workload. I tested tpcc 5000W (~500GB of data in InnoDB) on Clustrix systems with 3, 6, 9-nodes and also, to have base for comparison, ran the same workload […]

Multiple MySQL instances on Fusion-io ioDrive

It is known that MySQL due internal limitations is not able to utilize all CPU and IO resources available on modern hardware. Idea is to run multiple instances of MySQL to gain better performance on Fusion-io ioDrive card. Full report is available in PDF

White Paper: Flashcache and MySQL on Virident drive

Our latest MySQL white paper is Improving Percona Server performance with Flashcache on the Virident tachIOn Drive. (Virident funded the research, but as always, we wrote the report ourselves.) The conclusion is that Flashcache can be good for read-heavy workloads, but more research is needed to understand its performance characteristics on write-heavy workloads. We explain […]

Followup on performance metrics: slides, video

A while back, I wrote a two part post on how you can extract an amazing amount of information about a system’s performance, scalability, queueing, and more by just measuring request arrivals and completions, and the timestamps thereof. I promised to develop this into a more complete description of how to analyze MySQL’s performance and […]

Finding an optimal balance of I/O, CPU, and RAM for MySQL

For a long time I’ve wanted to know how MySQL scales as you add more memory to the server. Vadim recently benchmarked the effects of increasing memory and CPU core count. He looked for a balance between utilizing the hardware as much as possible, limiting the system complexity, and lowering the price-to-performance ratio. The outcome […]

White Paper: “Scaling MySQL Deployments Efficiently” from Percona and Virident

Percona was working closely with Virident on evaluating tachIOn as solution for MySQL, and as result you can find whitepaper “Scaling MySQL Deployments Efficiently Using Virident tachIOn Drives”, available from Virident website. It was done as part of our consulting practice, but all results and numbers are certified by Percona. I personally really enjoyed performance […]

Percona Server Fast-Restart White Paper Posted

I’ve posted a new white paper about the implementation and benefits of Percona Server’s fast-restart capabilities. Briefly, after shutting down and restarting or rebooting the server, it can be back to full performance in a couple of minutes. That’s minutes, not hours or days. This matters a lot for keeping uptime high and reducing hardware […]

Percona white paper: Forecasting MySQL Scalability

Ewen and I have just published Percona’s latest white paper, Forecasting MySQL Scalability with the Universal Scalability Law. This is essentially a streamlined walk-through of Dr. Neil J. Gunther’s book Guerrilla Capacity Planning, with examples to show how you can apply it to MySQL servers. One thing alluded to in the paper is extracting the […]

Goal-Driven Performance Optimization white-paper available

If you were at last month’s MySQL conference, you might have seen a small flyer we were distributing, titled “A brief introduction to Goal-Driven Performance Optimization.” This is a super-compressed technical introduction to one of the methods we use to solve problems as quickly and efficiently as possible. We’ve just posted this on a new […]
