HammerDB is a software application for database benchmarking. HammerDB has graphical and command line interfaces for the Windows and Linux operating systems. Databases are highly sophisticated software, and to design and run a fair benchmark workload is a complex undertaking. Why HammerDB was developed.

HammerDB is a load testing and benchmarking application for relational databases. On high-performance multi-core systems all the supported databases can return performance in the many millions of transactions per minute. Basic Benchmarking Concepts. To benchmark a database we introduce the concept of a Virtual User.

While many of us, designers and developers, are likely to have a relatively new mobile phone in our pockets, a vast majority of our customers isn’t quite like us. A performance benchmark Lighthouse is well-known. And to ensure the quality of a product, we always need to test — on a number of devices, and in a number of conditions.

One of the important attributes of their design was easy and rapid deployment across an existing fleet. Looking across a set of eight Java benchmarks, we find that only two of them are array dominated, the rest having between 40% to 75% of the heap footprint allocated to objects, the vast majority of which are small.

If queries perform full table scans where an index could be used or perform heavy joins or expensive aggregate operations, then the system can still perform poorly even if the database parameters are tuned. The PostgreSQL buffer is called shared_buffer which is the most effective tunable parameter for most operating systems.

Such information helps us design experiences for a higher retention rate. Which device brand do they use?
