When I published the MariaDB-5.3.4 sysbench results I said “if your workload includes complex (sub)queries, then you will probably benefit more from MariaDBs new optimizer features”. Today I will present some benchmark results for complex workload.
The benchmark is DBT3, an implementation of the TPC-H specification. DBT3 is written in C and hosted at Sourceforge.
The DBT3 benchmark can run at different scale factors – defining the size of the database. I used a scale factor of 30 which yields ~30GB of raw data and ~48GB of disk footprint. The machine running the benchmark had 16G of memory. …

MariaDB-5.5.21-beta is the first MariaDB release featuring the new thread pool. Oracle offers a commercial thread pool plugin for MySQL Enterprise, but now MariaDB brings a thread pool implementation to the community!
If you are not familiar with the term, please read the Knowledge Base article about it.
The main design goal of the thread pool is to increase the scalability of the MariaDB server with many concurrent connections. In order to test and demonstrate this, I have run the sysbench OLTP RO benchmark with up to 4096 threads to compare the new pool-of-threads and the traditional thread-per-connection scheduler:
Benchmark description:
- sysbench multi table OLTP, readonly
- 16 tables, totaling 40 mio rows (~10G of data)
- 16G buffer pool – result is independent of disk performance
- mysqld bound to 16 cpu cores, sysbench to the other 8
Read/write OLTP benchmark results will be published as soon as they are available. …
