We decided to run a few benchmarks to understand how the thread pool affects long-running transactions. This server is not intended to be a perfectly tuned one but just a baseline to compare the behavior under different concurrency configurations. For this reason, I’ve set up a server with the following specs: r6a.2xlarge

Perhaps the most interesting lesson/reminder is this: it takes a lot of effort to tune a Linux kernel. Google’s data center kernel is carefully performance tuned for their workloads. A micro-benchmark suite, LEBench was then built around tee system calls responsible for most of the time spent in the kernel. Headline results.
