The wikipedia page on floating point numbers describes a number of related accuracy problems including the difficulty of testing for equality. In day-to-day usage, beyond judicious use of ‘within’ for equality testing, I suspect most of us ignore the potential difficulties of floating point arithmetic even if we shouldn’t.

For the rest of us, if you really need that extra performance (maybe what you get out-of-the-box or with minimal tuning is good enough for your use case) then you can upgrade hardware and/or pay for a commercial license of a tuned distributed (RHEL). This causes average slowdowns of 66% across the select , poll , and epoll tests.

Arguably, the most common beginning errors with database benchmarking is for a user to select a single point of utilisation (usually overconfigured) and then extrapolate conclusions about system performance from this single point. The performance profile allows you to group these related TPROC-C workloads together with a single profile ID.
