In this blog I'm sharing the results of a series of tests designed to explore the impact of various MySQL and, in particular, InnoDB tunables. Performance engineers from Sun have previously blogged on this subject - the main difference in this case is that these latest tests were based on Linux rather than Solaris.

It's worth noting that MySQL throughput doesn't scale linearly as you add large numbers of CPUs. This hasn't been a big issue to most users, since there are ways of deploying MySQL successfully on systems with only modest CPU counts. Technologies that are readily available and widely deployed include replication, which allows horizontal scale-out using query slaves, and memcached, which is very effective at reducing the load on a MySQL server. That said, scalability is likely to become more important as people increasingly deploy systems with quad-core processors, with the result that even two processor systems will need to …

Over the past couple of days Sun has been getting a lot of feedback on it's behaviour with open source.

So there is Amanda McPherson trying to teach Sun that the L in LAMP really stands for Linux.

And then there was Roy T. Fielding quiting the Open Solaris community.
I'm still wondering why a company that once bought StarDivision because it was cheaper to buy the company than to pay licenses for similar functionality, keeps maintining their own kernel stack rather than contributing to one that is way more popular and as a much larger userbase.
Its not like they have a die hard community they will loose, it's not like they will loose customers over it. When Sun says that Linux is the new …

Recently we put together a consolidation benchmark to see how an open-source stack performs against the proprietary stack from Microsoft. Solaris, MySQL, and Sun Web Server running on the open-source UltraSPARC T2 processor were pitted against a Microsoft SW stack running on a 4-socket QC Xeon server. This benchmark highlights the continued trend to incorporate MySQL open-source databases and how it works under virtualization (Solaris Zones).

The Sun SPARC Enterprise T5220 (1.4 Ghz UltraSPARC T2 processor) and Solaris Containers managing a consolidation of Open-Source Software components (MySQL Database and Sun Java System Web Server) provided 2.4 times better performance than the HP DL580 system (four Xeon quad-core processors) and a major virtualization software, Microsoft Windows 2003 Server EE, Microsoft SQLserver database and Microsoft IIS webserver.

For a change, let me remind you of the upcoming MySQL Users Conference in Santa Clara. It’s less than two months from now; it’ll be from Monday 14 April 2008 to Thursday 17 April 2008. Same place as last year: Santa Clara, California, USA.

My reminder is triggered by the fact that tomorrow is the last day for Early Registration, by which conference participation costs 1299 instead of 1499 dollars (or, if you skip the Monday tutorials, 999 instead of 1199 dollars). In short, early registration saves you 200 dollars.

I do think the UC is at least as interesting as last year, and I’m very happy about our …

We recently integrated MySQL 5.0.45 version with Open Solaris. MySQL 5.0.45 is available in SXDE 01/08. Sun Studio was used to compile MySQL on both Solaris SPARC and Solaris AMD64 platform.

This blog entry describes the changes that were made to improve MySQL performance using Sun Studio:

• Enable function inlining when Sun Studio is used.
  • The header file univ.i has the following code:
    
    • #if !defined(GNUC) && !defined(WIN)
    • #undef UNIV_MUST_NOT_INLINE /* Remove compiler warning */
    • #define UNIV_MUST_NOT_INLINE
    • #endif
  •  Modifying it to add Sun Studio compiler as under:
    • #if !defined(GNUC) …

MySQL 5.0.45 is integrated with Open Solaris build 79. It is available in Solaris Express Developer Edition (SXDE) 01/08. MySQL 5.0.45 is integrated with Solaris Service Management Facility (SMF).

This blog entry describes the steps that were taken to integrate MySQL with SMF.

First a quick recap of what is SMF:

SMF is the core component of the predictive self-healing technology available in Solaris 10, which provides automatic recovery from software and hardware failures as well as adminstrative errors.
Some of the advantages of using SMF are as under:

• Failed services are automatically restarted in dependency order, whether they failed as the result of administrator error, software bug, or were affected by an uncorrectable hardware error.

• More information is available about misconfigured or misbehaving …
