btrfs – probably not ready yet

Every time I have a conversation on SSD, someone mentions btrfs filesystem. And usually it is colored as a solution that will solve all our problems, improve overall performance and SSD in particular, and it is a saviour. Of course it caught my curiosity and...

Intel 520 SSD in MySQL sysbench oltp benchmark

By Vadim Tkachenko

In my raw IO benchmark of Intel 520 SSD we saw that the drive does not provide uniform throughput and response time, but it is interesting how does it affect workload if it comes from MySQL. I prepared benchmarks results for Sysbench OLTP workload with MySQL...

Benchmarking single-row insert performance on Amazon EC2

By Ovais Tariq

I have been working for a customer benchmarking insert performance on Amazon EC2, and I have some interesting results that I wanted to share. I used a nice and effective tool iiBench which has been developed by Tokutek. Though the “1 billion row insert...

Testing Fusion-io ioDrive2 Duo

By Vadim Tkachenko

I was lucky enough to get my hands on new Fusion-io ioDrive2 Duo card. So I decided to run the same series of tests I did for other Flash devices. This is ioDrive2 Duo 2.4TB card and it is visible to OS as two devices (1.2TB each), which can be connected together...

New distribution of random generator for sysbench – Zipf

By Vadim Tkachenko

Sysbench has three distribution for random numbers: uniform, special and gaussian. I mostly use uniform and special, and I feel that both do not fully reflect my needs when I run benchmarks. Uniform is stupidly simple: for a table with 1 mln rows, each row...

By Vadim Tkachenko

In my previous post with results for Fusion-io ioDrive we saw some instability in results, I was pointed that it may be fixed in new drivers VSL 3.1.1. I am not sure if this driver is available for everyone – if you are interested, please contact your...

Testing Virident FlashMAX 1400

By Vadim Tkachenko

I still continue to run benchmarks of different SSD cards. This time I show numbers for Virident FlashMAX 1400. This is a MLC PCIe SSD device. There are couple notes on these results. First, this time I use a different server. For this benchmark it is Cisco...

Testing Fusion-io ioDrive

By Vadim Tkachenko

Following my series of posts on testing different SSD, in my last post I mentioned that SATA SSD performance is getting closer to PCIe cards. It really makes sense to test it under MySQL workload, but before getting to that, let me review the same workload...

Testing Intel SSD 520

By Vadim Tkachenko

Following my previous benchmarks of SATA SSD cards I got Intel SSD 520 240GB into my hands. In this post I show the results of raw IO performance of this card. The benchmark methodology I described in previous posts, so let me jump directly to results. First...
