As with most software-defined-storage solutions, Datrium DVX gains performance not only with faster servers and processors, but also with every new software release.</p>https://myvirtualcloud.net/postgresql-benchmark-on-datrium-4-3-million-tps-with-1-gb-ram-and-some-frustration/Mon, 12 Feb 2018 08:52:09 +0000https://myvirtualcloud.net/postgresql-benchmark-on-datrium-4-3-million-tps-with-1-gb-ram-and-some-frustration/<p><span style="font-weight: 400">Cutting to the chase, I want to share some benchmark numbers I have been able to run in our Solutions lab and demonstrate how Datrium DVX compares to other published figures. While some may claim that benchmarks can be gamed (and they can), I tried to stick to a simple formula that can be easily repeated by anyone on any platform for comparable results. Furthermore, the more hardware you throw at the problem, the more performance you will get, but generally if you fix as many variables as possible, the results should be within a reasonable margin.</span></p>
