[fpc-pascal] Why external execution so slow?

[Gabor Boros]

Hi All,

I need to execute an external program from my application. This 
execution is much slower than execute the external application from 
command line. I made a simple example (see below) which show 1.7 seconds
for me. Why? (From command line the execution time is 15 milliseconds. I 
used Windows 10 64bit.)

var
   Start:TDateTime;
   OS:String;
begin
   Start:=Now;
   RunCommandInDir('E:\FPC\3.2.0\bin\i386-win32','fpc.exe',['-h'],OS,[]);
   WriteLn(FormatDateTime('nn:ss.zzz',Now-Start));
