Looking on 5.4 – IO bound benchmarks

 | April 30, 2009 |  Posted In: Benchmarks

With a lot of talks around 5.4 I decided to check how it works in our benchmarks. For first shoot I took tpcc-like IO-bound benchmark (100W, ~10GB of data, 3GB buffer_pool) and tested it on our Dell PowerEdge R900 box (16 cores, 32GB of RAM, RAID 10 on 8 SAS 2.5″ 15K RPM disks). For […]

Call for opinions: Do we need MySQL 5.0 with MySQL 5.4 performance

 | April 29, 2009 |  Posted In: Events and Announcements

MySQL 5.4 comes with Innodb engine which seems to have much better performance than MySQL 5.0 – this is due to locking and IO patches from Google integrated in this release (which are similar to appropriate Percona patches) as well as some unique fixes such as different innodb_thread_concurrency handling and other optimization.

The Depth of a B-tree

 | April 28, 2009 |  Posted In: Tokutek, TokuView

Schlomi Noach recently wrote a useful primer on the depth of B-trees and how that plays out for point queries — in both clustered indexes, like InnoDB, and in unclustered indexes, like MyISAM. Here, I’d like to talk about the effect of B-tree depth on insertions and range queries. And, of course, I’ll talk about […]

Detailed review of Tokutek storage engine

 | April 28, 2009 | 

(Note: Review was done as part of our consulting practice, but is totally independent and fully reflects our opinion) I had a chance to take look TokuDB (the name of the Tokutek storage engine), and run some benchmarks.

 | April 26, 2009 |  Posted In: Tokutek, TokuView

The campus was known as The Great Asylum for the Insane in the 19th century, and even includes a tower. High Anxiety, whenever you’re near. High Anxiety, it’s you that I fear.
