Archive for category Uncategorized – default Thread quantity now self determined

There’s a new version of the dbbenchmark tool available. Now we’re creating the MySQL connection pool thread count based on automatic reporting of core quantity. There is still the same method to set the thread count manually if you are interested in finding your system’s thread limits. Download the MySQL benchmarking script now and add your server performance to the community database of results!

Tags: , , , – MySQL (basic) connection pool support added

In this latest release I’ve added a basic MySQL connection pool to the benchmarking script which improves the method in which connections to MySQL are handled and reused. In addition, there have been some optimizations made to the thread handler functions for better debug reporting. Download the latest release now and see how your MySQL server performs against the rest of the community! Download here: download page.

As previously mentioned, Darren Cassar has been working on a new automated installer for the DBbenchmark program. It’s now available for download: click here. All you need to do is save it to the directory that you want to install to and then make sure it’s executable: “chmod 700”, then run it “./”.

So far the benchmarking script supports Linux, FreeBSD, and OSX. I’m installing virtual machines today to get ready for development on the next OS that the community wants to have supported. Vote today for your choice. Development will begin Friday 2010-09-03.

Tags: , , , , , , – MySQL benchmarking now with FreeBSD support

The development cycle is moving right along for the community’s newest MySQL benchmarking script. I’m pleased to announce that we now officially support FreeBSD (version 8.1 tested) so go ahead and download now and test your FreeBSD, Linux, or OSX MySQL server! Click here for the download.

Courtesy of Darren Cassar and some generous coding this weekend, we’re going to be releasing a auto-installer / updater for the application which you can use to automate that part of the process. Stay tuned for information on that release.

Tags: , , , , , , – Debian Lenny, MEMORY_ACTIVE bug fix

Quick solution to an issue that the affected Debian Lenny release: the process used to collect the MEMORY_ACTIVE_BYTES variable has been modified to correct a situation where some systems report an array of memory information instead of the expected single integer value. The bug has been fixed in revision 21 and the current download (revision 22) is available for download or svn update. As usual, you can download the MySQL dbbenchmark script here: [downloads].

Thanks goes to Brian Vowell at for bringing this bug to my attention. The original bug report can be found here: [link]

Tags: , , , , , – MySQL benchmarking now supports multiple threads!

We had a very successful weekend of Planet.mysql users submitting their database statistics so I’ve pushed some code into a new release today so that everyone can benefit from some new features. The biggest change is to the threading logic. Previously the benchmarking script was serializing MySQL operations and only making use of a secondary thread (not the invoking thread) to query the database. Now you have the option of running with “–threads=x” to make use of your multi-core server. A good example of this improvement was on my Macbook Pro; before the threading change it was inserting ~700/sec, after the code change I tried –threads=4 and saw an improvement to ~900/sec. Rather significant.

Download the new script now and see how your server compares to the ones in the central database!

Tags: , , , , , , , , – now supporting MySQL on OSX 10.6

Just a quick note to let everyone know that our new benchmarking script now supports OSX 10.6 on Intel hardware. That means you can run one simple command and get all of the sequential and random INSERT and SELECT performance statistics about your database performance. As usual the script is open source and released under the new BSD license. Give is a try by downloading now! See the download page for more details.
