newbie people wants some advice.

sir, i use ubuntu and somehow I also precompiled my header. So after 1st run it generates output in mili second(despite any change at testcase or slight change in code), but while running a completely new problem code and test case for the first time it takes almost 10 seconds. is it might be cause I have only 4gb ram and no ssd?
