Olio on 6-core Opterons (Istanbul) based Sun Systems
Employee +0 Vote Up -0Vote Down

Sun is launching systems with multisocket  6-core Opterons (Istanbul) today. Last week I got access to  Sun Fire X4140 with 2 x 6-core Opterons with 36GB RAM. It is always great to see such a 1RU system packaged with so many x64 cores.

MySQL Performance: Why Ahead Flushing for InnoDB?...
Employee +2 Vote Up -0Vote Down

Recently I've done several performance studies to find the most optimal way to fix the "furious flushing" observed during all my benchmarks with InnoDB. The initial report about this work you may find here including initially proposed patches. But analyzing test workloads with the latest MySQL performance build I think there is a need to go more far...

First of all let's me present you the result I've got on the Read+Write workload @dbSTRESS - first part of graph represents the TPS level obtained with MySQL 5.4, and the second part - …

MySQL Performance: Once again about InnoDB thread concurrency...
Employee +2 Vote Up -0Vote Down

Even this topic was covered several times already, the question is still open - use or not to use InnoDB thread concurrency?.. And the only true answer here - "It depends" :-) and I'll try to make a short summary about the current state here.

The main current InnoDB bottlenecks are all mostly due to a high contention on internal locks. As all multi-threaded (as well multi-process) applications giving a concurrent access to its resources, InnoDB have to guarantee there is only one thread may modify a given resource on the same time. This guarantee is achieved by locking a resource in exclusive mode and implemented with mutexes. Depending on …

+0 Vote Up -0Vote Down

Absolutely nothing?

5.4.0 was released with a change in the MySQL Binary distributions, delivering only 1 64bit Linux platform and two Sun Solaris platforms. This was officially announced on April 21 2009 however the 5.4.0 Release Notes state 05 April 2009. So it’s not a big deal, but consistency would be nice.

I’ve seen in a few posts 5.4.1, so I …

Employee +1 Vote Up -0Vote Down

Recently new performance builds were made by our MySQL Team, and it seems to me reaching now a new milestone with the build #45 - within this single build Mikael joined several previously tested performance builds showed a positive performance improvement. So, how well it's comparing now to the default 5.4 ?..

Here are my results obtained on M5000 (quad-cores)/ Solaris10 update7 and db_STRESS.

Solaris 10 update7

Special note about update7: I was pleasantly surprised the …

Business Intelligence Using Open Storage
+0 Vote Up -0Vote Down

Sun recently rolled out a new Business Intelligence (BI) solution that uses Open Storage at its core. There are several things that are different about this solution that make it stand out from the crowd.

1) It is based on Open Source software.

This solution uses the commercial versions of open source software from Pentaho and Infobright to provide the BI and Datawarehouse (DW) functions respectively and both use the MySQL database. Also, this solution uses Sun's Open Storage …
