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 important choice you will still have to make is what type and size of Azure virtual machine you want to use for your existing SQL Server workload. Microsoft currently has eight main types of virtual machines designed for different types of workloads. Azure VM Types and Series. Hopefully, they will do that in the future. Conclusion.

HammerDB uses stored procedures to achieve maximum throughput when benchmarking your database. HammerDB has always used stored procedures as a design decision because the original benchmark was implemented as close as possible to the example workload in the TPC-C specification that uses stored procedures. performance advantage.

OS maintains a huge list of allocated and free pages to make slow but reliable address translation from virtual to physical. Huge pages make PostgreSQL faster; can we implement it in Kubernetes?

Predicting application performance is a difficult art, but an important one when choosing the target deployment environment. Regardless of whether the computing platform to be evaluated is on-prem, containerized, virtualized, or in the cloud, it is crucial to consider several essential factors. For storage, FIO is generally used.

Some older kernels have the KAISER patches for Meltdown, and so far the performance overheads look similar.

I'm sure this delivered large performance improvements and I wouldn't try arguing against it.

This is an important consideration that is often missed, so although it seems obvious, it is worth reiterating that benchmarking applications are not typically designed to be disconnected and the database restarted whilst the workload is running.
