Unfortunately, using certain open source database software as part of an HA architecture can present significant challenges. Despite all its upside, PostgreSQL software presents such challenges. HA in PostgreSQL databases delivers virtually continuous availability, fault tolerance, and disaster recovery.

HammerDB is a software application for database benchmarking. It enables the user to measure database performance and make comparative judgements about database hardware and software. Databases are highly sophisticated software, and to design and run a fair benchmark workload is a complex undertaking. The HammerDB name.

Here, virtual(logical) to physical address translation is much easier as segment tables store adequate information. Copyright (C) 2020 Free Software Foundation, Inc.

Among the different components of modern software solutions, the database is one of the most critical. 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. Instead, readers should refer to the HammerDB documentation.

This post explains why HammerDB made the language decisions it made to make it the best performing and most usable database benchmarking software. To benchmark a database we introduce the concept of a Virtual User. So having an application client mutex lock that artificially stalls our Virtual Users does not sound good.
