XtraDB/InnoDB CPU bound benchmarks on 24cores server

One of our customers gave me a chance to run some benchmarks on 24-core (intel cpu based) server, and I could not miss it and ran few CPU-bound tasks there. The goal of benchmarks was investigation of InnoDB-plugin and XtraDB scalability in CPU-bound load.

Using sysbench 0.5 for performing MySQL benchmarks

Given the recent excitement & interest around OpenStack I wanted to make sure I was ready to conduct appropriate evaluations of system performance.  I generally turn to sysbench since it comes with a variety of different tests (accessed via –test= option interface), including: fileio – File I/O test cpu – CPU performance test memory – […]

Benchmarks of Intel 320 SSD 600GB

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.

Benchmarks of new innodb_flush_neighbor_pages

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.

Aligning IO on a hard disk RAID – the Benchmarks

In the first part of this article I have showed how I align IO, now I want to share results of the benchmark that I have been running to see how much benefit can we get from a proper IO alignment on a 4-disk RAID1+0 with 64k stripe element. I haven’t been running any benchmarks […]

Looking on 5.4 – IO bound benchmarks

With a lot of talks around 5.4 I decided to check how it works in our benchmarks. For first shoot I took tpcc-like IO-bound benchmark (100W, ~10GB of data, 3GB buffer_pool) and tested it on our Dell PowerEdge R900 box (16 cores, 32GB of RAM, RAID 10 on 8 SAS 2.5″ 15K RPM disks). For […]

XtraDB in CPU-bound benchmark

Peter said me that previous results http://www.percona.com/blog/2008/12/18/xtradb-benchmarks-15x-gain/ are too marketing, and we should show other results also. Here is the run for CPU Bound,or it would be more correctly to say in-cache benchmark, because there is a lot of CPU remains idle. This run is exactly the same as Disk Bound but with innodb_buffer_pool_size=8G which […]

XtraDB benchmarks – 1.5X gain in IO-bound load

I guess it is first reaction on new storage engine – show me benefits. So there is benchmark I made on one our servers. It is Dell 2950 with 8CPU cores and RAID10 on 6 disks with BBU, and 32GB RAM on board with CentOS 5.2 as OS. This is quite typical server we recommend […]

MySQL QA Team Benchmarks for MySQL 5.1.30

As you might have seen MySQL QA Team has published their benchmarks for MySQL 5.0.72 and 5.1.30. It is interesting to compare with results I posted previously

MySQL 5.0, 5.1 and Innodb Plugin CPU Efficiency

We’ve recently done benchmarks comparing different MySQL versions in terms of their CPU efficiently in TPC-C like Workload. We did it couple of weeks ago so MySQL 5.0.67, MySQL 5.1.29 and Innodb Plugin 1.0.1 were used which are not very recent, though we do not think results will differ a lot with today versions.
