Python is a popular programming language, especially for beginners, and consequently we see it occurring in places where it just shouldn’t be used, such as database benchmarking. We use stored procedures because, as the introductory post shows, using single SQL statements turns our database benchmark into a network test).

One of the most important concepts in analysing database performance is that of understanding scalability. Plotting these data points enables us to understand the scalability of the database software being tested on that system. In particular, this means as we add CPU cores and increase the system load, we see higher performance.

Coupled with stateless application servers to execute business logic and a database-like system to provide persistent storage, they form a core component of popular data center service archictectures. Why are developers using RInK systems as part of their design? We’ve seen similar high marshalling overheads in big data systems too.)

We had specializations in hardware, operating systems, databases, graphics, etc. Jim Mauro and Allan Packer visited on rotation from New Jersey, and Adelaide Australia, and worked out how to produce a database sizing guide for Oracle Financials, which I wrote up and published. Jim also joined the database performance team.

However if you have downloaded the source code and are looking to add features or make modifications such as adding new databases you may be wondering once you have the source code where to start. However HammerDB will not be able to connect to a database yet and the librarycheck command included with the CLI gives an indication why.
