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.
Following my previous benchmark of Samsung 830, today I want to show results for STEC MACH16 SATA card, 200GB size, this card is based on SLC, and regarding STEC website, it is an enterprise grade storage.
I personally like PCIe based Flash, but from a pricing point our customers are looking for cheaper alternatives. SATA SSD is an options. There is many products based on MLC technology, and Intel 320 I would say is the most popular. I do not particularly like its write performance – I wrote about it before, […]
As ext4 is a standard de facto filesystem for many modern Linux system, I am getting a lot of question if this is good for SSD, or something else (i.e. xfs) should be used. Traditionally our recommendation is xfs, and it comes to known problem in ext3, where IO gets serialized per i_node in O_DIRECT […]
Traditionally the most benchmarks are focusing on throughput. We all get used to that, and in fact in our benchmarks, sysbench and tpcc-mysql, the final result is also represents the throughput (transactions per second in sysbench; NewOrder transactions Per Minute in tpcc-mysql). However, like Mark Callaghan mentioned in comments, response time is way more important […]
If you are terrified by the stability of the results in MySQL in my previous post, I am going to show what we can get with Percona Server. This is also to address the results presented there Benchmarking MariaDB-5.3.4
I have a chance to test a system with Intel 320 SSD drives (NewRelic provided me with an access to the server), and compare performance with SAS hard drives.
On coming PL MySQL conference 2012 I will give one tutorial: Percona XtraBackup: install, usage, tricks. This tutorial I will do in joint with Alexey Kopytov, the lead developer of Percona XtraBackup. Our intent is to provide the comprehensive overview of the XtraBackup architecture and features, and we will touch future roadmap. This is all […]
In our recent release of Percona Server 5.5.19 we introduced new value for innodb_flush_neighbor_pages=cont. This way we are trying to deal with the problem of InnoDB flushing.
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 […]
