c# - Action faster than method call? -


Some time ago I came to know about a method that the action is faster than the pure method call. I do not remember where it is, but had to move in the moment, did some tests and found that it tells the truth in some cases.

Someone today says that what I was doing was wrong, so anyone can get a reason, in these tests, the work of the parameters is faster than pure methods? I must say that this is only faster in x64 machines, slow in x86. 

  class program {static zero main (string [] args) {test t = new test (); T.doTest (); Console.ReadKey (); }} Class test {stopwatch w; int a = 0; Public zero doTest () {action doSum = () = & gt; {A = A + 1; }; & Lt; Integer & gt; DoSumValue = (plus) = & gt; {A = A + add; }; w = new stopwatch (); Console WrightLine ("------- with params -------"); {A = 0; for intented = 0; round and lieutenant; 10; round ++) W.Reset (); w.Start (); For (Intubsee = 0; Books & lt; 500000000; buc ++) Sum (1); w.Stop (); Console.light line ("function:" + w. Applied milliseconds); A = 0; W.Reset (); w.Start (); For (Intubsee = 0; Booky <50,0000000; buc ++) doSumValue (1); w.Stop (); Console.light line ("Action:" + w.ElapsedMilliseconds); } Console. WrightLine ("-------- Without a parameter ---------"); {A = 0; for intented = 0; round and lieutenant; 10; round ++) W.Reset (); W.Start (); For (intubic = 0; bouquet; lt; 500000000; buc ++) yoga (); w.Stop (); Console.light line ("function:" + w. Applied milliseconds); A = 0; W.Reset (); w.Start (); For (Intubsee = 0; Booke> 50,0000000; buc ++) doSum (); w.Stop (); Console.light line ("Action:" + w.ElapsedMilliseconds); }} Zero sum () {a = a + 1; } Zero sum value (atad) {a = a + toAdd; }}   
  Edit: changes to the loop count for surpacing 1 second with the same result   
 Results on my machine (I7 2600) are:  
  New results with many details   
 with -x86 * parameter  
 Function: 1417ms Action: 1568ms  
 * Without parameters  
 Function: 1422ms Action: 1634ms  
 - x64 * with parameter  
 Function: 1 9 76ms Action: 2114ms  
 * Without parameters  
 Function: 1975ms Action: 1719ms  
  Less text C Old results with OUNT   
  with -x86 parameter   
 Function: 28ms  
 Action: 31ms  
  without -x86 parameter   
 function: 28ms  
 Task: 32ms  
  -x64 parameter   
 Function: 39ms  
 Action: 42ms  
  with -x64 parameter   < P> 
  Function: 39ms   
  Action: 34ms   
 So, whether my test is incorrect or the parameters of parameter parameters in x64 machines Are faster work than calls?  
  
 
 
  verb {/ code> is a representative, for all purposes and purposes in NAT , There is only one method indicator. That is, it is an indicator for a method, so logically it makes the same basic instructions and calls a method under cover. There is no reason to  normal  the reason that the action written by the action action will be faster than the call. There are many scenarios where it can be a little slow as it is the level of intuition around a method call - but not in a meaningful way.
