Hadrian performance

The sortable table below presents mean and standard deviation (stdev) times spent computing each PFA function in isolation. The "(nothing)" special case is a PFA engine that simply returns null and the "(pass-through)" special case is a PFA engine that simply outputs what it is given. These represent the overhead of the PFA action itself, while the tests of each function should be understood as being relative to this baseline (within a standard deviation).

Each mean and standard deviation is based on all the conformance tests, which cover a broad spectrum of input types (for functions with wildcards) and input values, and each input value was tested hundreds of times. The effect of HotSpot just-in-time optimizations was avoided by instituting a burn-in period, and the effect of the Java garbage collector was avoided by invoking the garbage collector when the stopwatch is off (when the heap memory used reaches 5 GB in a JVM with a maximum of 8 GB).

Means and standard deviations are split into two cases: ones which result in a value (no errors) and ones that raised an exception.

All tests were performed on an AWS m3.xlarge instance (4 vCPU Intel Xeon E5-2670 v2 processors, 15 GB SSD-based RAM) running Ubuntu 14.04 (Trusty Tahr) and Oracle Java version 1.8.0_40 (64-bit build 25.40-b25) with -Xmx8g -Xmn8g to ensure the fixed memory allocation that allows us to control garbage collector calls.
