SUMMARY<\/h1>\n

From the last two\u00a0articles(profile with gprof<\/a>,\u00a0profile with oprofile<\/a>), you may know some experiences of profile with C\/C++ program. So let’s take a look at a new tool from google, called “gperftools<\/a>“, full name is “Google performance tools”.<\/p>\n

What are the differences?<\/h1>\n

We know gprof and oprofile, but why gperftools? Ok, take it easy, easy… Let me show you all:<\/p>\n

First, we know gprof need to re-compile the program with “-pg”, it’s not a system profile tool, and it do multiple threads profile so hard and sometimes it’s not so precise. However, oprofile can solve them much easier, but it always shows all program results during the profile time, and we need the permission of sudo.<\/p>\n

So, you can take the gperftools if you want to do profile with a multiple threads program without permission of sudo. I think it’s a much better choose than these two tools. Another reason why you choose it is that gperftools can generate a nice graph by itself. So, why not? :D just try it.<\/p>\n
