[Lazarus] LNet component Event vs thread ? faster or more reliable?

[Boian Mitov]

Threads can lead to significant performance gain even on a single core, if 
used properly. Used incorrectly however they will lead to a slower execution 
if nothing else due to time lost in switching, cache flushing and thread 
synchronization. In multicore the performance gain can be huge, but the 
danger of lost performance due to bad thread synchronization still exists.
Almost every single application I have written in the last 12 years has been 
multithreaded at least partially. Multithreading can offer a lot if used 
properly.

  With best regards,
