Fix: improve performance #13

Closed Spaier closed 6 years ago

Spaier commented 6 years ago

Tried to increase performance with:

  1. Using PLINQ instead of LINQ.
  2. Removing redundant list creation because we can just use ToList().
  3. Using Task.WhenAll to parallelize task execution. While ConfigureAwait(false) caused to continue execution of other threads, 3 tasks weren't executed in parallel. Visualization of how ConfigureAwait(false) works: https://blogs.msdn.microsoft.com/benwilli/2015/09/10/tasks-are-still-not-threads-and-async-is-not-parallel/

Hi, thank you, it looks good, I'll to check all before the weekend using "Performance Profiler" and merge this changes if the result will take a positive effect.

Thank you for the contribution, the code became more concise, but the changes did not affect the performance. Therefore, these changes will not lead to the release of the new version.
