Benchmarking MySQL ACID performance with SysBench

A couple of question I get a lot from MySQL customers is “how will this hardware upgrade improve my transactions per second (TPS)” and “what level of TPS will MySQL perform on this hardware if I’m running ACID settings?” Running sysbench against MySQL with different values for per-thread and global memory buffer sizes, ACID settings, and other settings gives me concrete values to bring to the customer to show the impact that more RAM, faster CPUs, faster disks, or cnf changes have on the server. Here are some examples for a common question: “If I’m using full ACID settings vs non-ACID settings what performance am I going to get from this server?”

Let’s find out by running sysbench with the following settings (most are self explanatory – if not the man page can explain them):

  • sysbench –test=oltp –db-driver=mysql –oltp-table-size=1000000 –mysql-engine-trx=yes –oltp-test-mode=complex …

How to get colored output from ‘ls’ on Solaris10

For all of those linux users out there that have moved over to, or tried out, Solaris10 or OpenSolaris because they heard the tales of how MySQL is faster on Solaris… or perhaps you wanted to learn how to use Sol10 for the great features of Zones or the ZFS filesystem? Regardless of why you’re on it you are probably wondering why Linux has colored output of filenames and directories but Solaris does not. The question of ‘why?’ isn’t important, but how to enable colors is. It’s very simple, and here’s how I fixed it. This is a result of digging through multiple semi-related links on Google.

  1. Download all packages from
    • dependency: libintl-3.4.0-sol10-x86-local

Reviewed: Python Testing by Daniel Arbuckle

I’ve recently had the pleasure of reading “Python Testing: An easy and convenient approach to testing your python projects” from Packt Publishing. It’s been a quick read but a solid set of instructions on the different methods for the subject.

The book starts out very quickly with details about the various methods that are available, the means of automation for testing, and of course the environment you’d want to be in for working on the subjects that the book covers. It then, in the second chapter, moves into the guts of testing by describing the basics of doctest via syntax and some simple examples, and then moves on to a real world example via the AVL tree. It’s all very basic testing until chapter three where the author gets into unit testing, …

Kontrollbase – revision 297 fixes Reporter-CLI “alert_22″ sub-routine

Quick note to let our users know that there was an XML tag closure error on the “alert_22″ subroutine in the “bin/” script. This does not affect the webapp portion of Kontrollbase – only reports generated via the command line reporter script. It is not a fatal error but will cause the XML file to […]

Kontrollkit – new backup script is partition space aware

I’ve been wanting to write a backup script for a while now that does the following: reads the partition information for the directory that you are backing up into and computes the used/available/percentage-available space. Then it reads the total data size from the MySQL tables and ensures that you have enough space on disk (for [...]

Kontrollbase – graph “no data to display” on new install has been fixed

If you have been wondering why the overview and graphs pages say “no data to display” on the graphs when you first install Kontrollbase, it’s because there’s no data in the database being returned from the queries that generate the graphs – this is because a new install has no data to graph. This has […]

Having an issue with a Kontrollbase upgrade?

If you’ve noticed that your recent upgrade did not go as planned and now the application does not load – please check this page: for notes on upgrades between versions. Typically you need to execute a SQL file against the current schema to bring it up to date. If you have any questions please [...]

Kontrollcomm – remote database and system command execution webapp

I’m pleased to announce the first release of Kontrollcomm – “The Server Command Automation Interface” is a web-based application that automates remote command execution on linux and unix based servers. There are three main areas of the application: Hosts, Templates, and Commands. The use is very simple: all of your hosts are setup in the [...]

Kontrollbase rev292 gets important UI layout fixes

This is a small revision and will only be available through SVN. However, it is an important one to speak about as it solves a former issue when running the application on a screen smaller than 1024px wide. While most users may not have noticed this since they have larger monitors it has been noticed [...]
