Benchmark protocol

#1 PHP FPM is restarted, to clear OPCache
#2 Clear all caches and logs, warmup caches if needed
#3 First unsaved benchmark is launched, 1,000 calls, concurrency 1, to init caches and fill OPCache
#4 5 benchmarks are launched, 50,000 calls, for each concurrencies (1, 5, 10 and 20)
#5 Only best results are added to Score, for each concurrencies



Best benchmark update benchmarked tool score.
This score is the sum of requests per second of all benchmark types (Hellow World, Rest API etc)
for all concurrencies (1, 5, 10 et 20).

The higher it is, the more the tool is able to respond quickly.
