Fix benchmark settings

[hadashiA]

Fix the settings of other libraries used for benchmarking. Also, make a few adjustments to ensure the same conditions as ZLogger.

Problem with log messages dropping

• NLog
  • NLog's AsyncTargetWrapper ignores messages that exceed the queueLimit by default.
  • https://github.com/NLog/NLog/wiki/AsyncWrapper-target
  • -> AsyncTargetWrapperOverflowAction set to .Grow.
  • -> queueLimit set to default (10000).
• Serilog
  • Serilog's BackgroundWorkerSink also drops messages that exceed the bufferSize.
  • -> bufferSize set to max value.
    • If bufferSize is exceeded, there are only two choices: drop or block the Log write side. Therefore, blockWhenFull is set to false (default) and bufferSize is increased.

Other settings

• NLog
  • refs
  • AsyncTargetWrapper
    • https://github.com/NLog/NLog/wiki/AsyncWrapper-target
  • FileTarget
    • https://github.com/NLog/NLog/wiki/File-target
  • Seeping
    • By default, it seems to wait and batch writes for 1 ms.
    • -> AsyncTargetWrapper.TimeToSleepBetweenBatches set to 0 to match other loggers.
  • Flushing
    • -> FileTarget.AutoFlash is set to true
      • This is the same as ZLogger's behavior, and it flushes for each dequeued messages group.
    • -> FileTarget.KeepFileOpen set to true.
    • -> FileTarget.ConcurrentWrites set to false.
• Serilog
  • Flushing
    • If buffered is set to true, Serilog does not seem to do explicit flushes. This is probably not fair.
    • -> flushToDiskInterval set to 0.
    • First I tried setting flushToDiskInterval to 1 ms, but Serilog would hang..

Thank you, it's the perfect setup just as I had in mind! It would be great to let more people know that ZLogger is set by default for reconsidering performance settings.
