Added some FlameGraph's for some of the optimizations (collected on a 24-core
Linux machine) when running the {{Process_BENCHMARK_ThroughputPerformance}}
benchmark.
Notation:
'no-lifo' implies using the {{DecomissionableKernelSemaphore}} (surprisingly
bad performance on Linux!)
'lifo' implies using the {{DecomissionableFixedSizeLifoSemaphore}} (added in
review https://reviews.apache.org/r/61069)
'lifo-message' implies 'lifo' + optimizing construction of {{MessageEvent}}
(added in patch https://reviews.apache.org/r/61067)
'lifo-message-cow' implies 'lifo-message' + copy-on-write optimization in
{{UPID}} (added in patch https://reviews.apache.org/r/61068)
The '2x' prefix implies that we ran the same benchmark except with twice the
number of client/destinations than the total number of cores on that machine.
