Tests include encryption, compression, fast Fourier transform, memory operations, n-body physics, matrix operations, histogram manipulation, and HTML parsing. GeekBench 4: LinkĪs a common tool for cross-platform testing between mobile, PC, and Mac, GeekBench is an ultimate exercise in synthetic testing across a range of algorithms looking for peak throughput. The AMD CPUs do really well in the sha256 test due to native support for SHA256 instructions.

This test produces a lot of graphs, so for full reviews I might keep the rsa2048 ones and just leave the sha256/md5 data in Bench. However, the ability to adjust how many threads are in play does work, which is important for multithreaded testing. OpenSSL speed has some commands to adjust the time of the test, however the way the script was managing it meant that it never seemed to work properly. For our last benchmark suite I scripted up enabling WSL with Ubuntu 18.04 on Windows in order to run SPEC, so that stays part of the suite (and actually now becomes the biggest pre-install of the suite).

To automate this test, Windows Subsystem for Linux is needed. OpenSSL offers a lot of algorithms to choose from, and based on a quick Twitter poll, we narrowed it down to the following:įor each of these tests, we run them in single thread and multithreaded mode. Luckily OpenSSL in Linux has a function called ‘speed’ that allows the user to determine how fast the system is for any given hashing algorithm, as well as signing and verifying messages. One of our readers reached out to me and stated that he was interested in looking at OpenSSL hashing rates in Linux. In our last review, and on my twitter, I opined about potential new benchmarks for our suite. Due to requests from a number of our readers, we have the following synthetic tests.

Synthetic tests are often very good at burrowing down to a specific set of instructions and maximizing the performance out of those. On the one hand, they’re often good for quick summaries of performance and are easy to use, but most of the time the tests aren’t related to any real software. Most of the people in our industry have a love/hate relationship when it comes to synthetic tests.
