As a followup to my MySQL 5.4 Scalability on 64-way CMT Servers blog, I'm posting MySQL 5.4 Sysbench results on the same platform. The tests were carried out using the same basic approach (i.e. turning off entire cores at a time) - see my previous blog for more details.

The Sysbench version used was 0.4.8, and the read-only runs were invoked with the following command:

sysbench --max-time=300 --max-requests=0 --test=oltp --oltp-dist-type=special --oltp-table-size=10000000 \
   --oltp-read-only=on --num-threads=[NO_THREADS] run

The "oltp-read-only=on" parameter was omitted for the read-write tests. The my.cnf file listed in my previous blog was also used unchanged for these tests.

Here is the data presented graphically. Note that the number of vCPUs is the same as the number of active threads up to 64. Active threads beyond …

Today Sun Microsystems announced MySQL 5.4, a release that focuses on performance and scalability. For a long time it's been possible to escape the confines of a single system with MySQL, thanks to scale-out technologies like replication and sharding. But it ought to be possible to scale-up efficiently as well - to fully utilize the CPU resource on a server with a single instance.

MySQL 5.4 takes a stride in that direction. It features a number of performance and scalability fixes, including the justifiably-famous Google SMP patch along with a range of other fixes. And there's plenty more to come in future releases. For specifics about the MySQL 5.4 fixes, check out Mikael Ronstrom's blog.

So how well does MySQL 5.4 scale? To help answer the question I'm going to take a look at some performance data from one of Sun's CMT systems based on the UltraSPARC T2 chip. This …

Sun recently announced the Sun SPARC Enterprise T5120 and T5220 and Sun Blade T6320 systems based on the UltraSPARC T2 processor.  You can find lots of information on the various features and functionality provided by these servers.

One other cool feature is that these systems ship with Cool Stack pre-loaded. The Cool Stack 1.1 packages are available in /var/spool/pkg. You can install the ones you want using the pkgadd(1M) command as follows :

root@wgs40-82 # cd /var/spool/pkg
root@wgs40-82 # ls
CSKampSrc_sparc.pkg        CSKphplibs_sparc.pkg

Sun engineers give the inside scoop on the new UltraSPARC T2 systems

[ Update Jan 2008: Sun SPARC Enterprise T5120 and T5220 servers were awarded Product of the Year 2007. ]

Sun launched the Chip-Level MultiThreading (CMT) era back in December 2005 with the release of the highly successful UltraSPARC T1 (Niagara) chip, featured in the Sun Fire T2000 and T1000 systems. With 8 cores, each with 4 hardware strands (or threads), these systems presented 32 CPUs and delivered an unprecedented amount of processing power in compact, eco-friendly packaging. The systems were referred to as CoolThreads servers because of their low power and cooling requirements.

Today Sun introduces the …
