HammerDB

FEBRUARY 25, 2021

HammerDB is a load testing and benchmarking application for relational databases. However, it is crucial that the benchmarking application does not have inherent bottlenecks that artificially limits the scalability of the database. Basic Benchmarking Concepts. To benchmark a database we introduce the concept of a Virtual User.

If you are not already familiar with the programming languages that HammerDB uses, then this earlier post serves as an ideal introduction to what makes up the highest performing GIL free database benchmarking application. For Db2 either the server or client can be installed, for example v11.5.7_linuxx64_server_dec.tar.gz.

Some opinions claim that “Benchmarks are meaningless”, “benchmarks are irrelevant” or “benchmarks are nothing like your real applications” However for others “Benchmarks matter,” as they “account for the processing architecture and speed, memory, storage subsystems and the database engine.”

is the refactoring of the stored procedures for some of the TPROC-C workloads. The TPROC-C workload is derived from the TPC-C workload , the primary metric for TPC-C is called tpmC, the number of new order transactions processed per minute. For SQL Server note that a change in the TPM metric was introduced at v3.3

HammerDB is open source and all of the source code is available at the sourceforge Git development site here [link] or the github mirror here [link]. In fact all of this source code is also included in readable form with each and every release. These bin and lib directories are not included with the source code.

Let’s examine the TPC-C Benchmark from this point of view, or more specifically its implementation in Sysbench. The illustrations below are taken from Percona Monitoring and Management (PMM) while running this benchmark. Analyzing read/write workload by counts. Analyzing Read/Write Workload by Response Time.

These services use requests to external hosts (not servers you control) to deliver JavaScript framework libraries, custom fonts, advertising content, marketing analytics trackers, and more. They are more of a benchmark than a true measurement of real user experience. You’ve thought of everything… or have you?

The unstoppable rise of open source databases. One database in particular is causing a huge dent in Oracle’s market share – open source PostgreSQL. See how open source PostgreSQL Community version costs compare to Oracle Standard Edition and Oracle Enterprise Edition. What’s causing this massive shift?

The project consisted of upgrading the shop software to our own open-source system and redoing the shop’s front end from scratch. Today, the website is much faster and ranks highly in various showcases and benchmarks. Working with jewellerybox on its online store was a welcome change of pace for us. Large preview ).

In the end, it’s not the load events or server response times that define the experience, but the perception of how snappy the interface feels. There are many tools allowing you to achieve that: SiteSpeed.io
