GCC (Linux) HELP NEEDED

Higher score is better. [2, 64] / (sample size / count).

Running the benchmark outputs all the necessary markdown used to update these results. All that is required is a proper GCC environment! (wait does the cmake file even work?)

Benchmark Algorithms

The individual benchmark algorithms are completely generic through the use of templates.

Algorithm Description
validation_assert Make sure each signal implementation is functioning correctly.
construction Sample the default construction of N * N number of Signal instances.
destruction Sample the destruction of N * N number of Signal instances.
connection Sample Signal connections to N number of Foo instances.
disconnect Sample disconnecting N number of Foo instances from a single Signal.
reconnect Sample reconnecting N number of Foo instances to a global Signal.
emit Sample the duration of an N slot emission.
all Sample all previous benchmarks together in one combined benchmark.
threaded Same as the previous benchmark but is now threaded.
