For better CPU analysis, you should use Time profiler in XCode Instruments.

Put an NSLogat the beginning of the method and one at the end

the console shows the exact time for the NSLog so thats how you can determine which takes log time

Example:

-(void)buttonsTag{
  NSLog(@"Beginning of buttonsTag Method");
  btn1.tag  =1;
  btn2.tag  =2;
  btn3.tag  =3;
  btn4.tag  =4;
  btn5.tag  =5;
  btn6.tag  =6; 
  btn7.tag  =7;
  btn8.tag  =8;
  btn9.tag  =9;
  btn10.tag =10;

  NSLog(@"End of buttonsTag Method");

}


 //The console output:
 //2012-10-10 14:22:29.308 APP[3691:c07] Beginning of buttonsTag Method
 //2012-10-10 14:22:29.309 APP[3691:c07] End of buttonsTag Method
 //The deference is 14:22:29.309 - 14:22:29.308 = 00:00:00.001
