My program consumes 3-4 times more CPU on Ubuntu 16.04 than on Windows, this task is NOT for new beginners or people who know simple if and else statements, this task is for people who have done profiling before and will be able to perform profiling now, and if you haven't done profiling before, please refrain from posting.

I am very proficient in c and c++. I have 16 years c++ developing experience now, and have worked for more than 7 years. My work is online game developing, and mainly focus on server side, using c++ under Linux environment. I made many great projects using c++, for example, I made the tools which could convert java codes into c++ scripts, of course garbage collection included, this was very similar to a compiler, and was very complex. I also made our own mobile game using c++, I can show you the demo of client, if you like. I am very proficient in java also. I have a very good review on Freelancer.com, I never miss a project once I accept the job, you can check my review. Trust me, please let expert help you.

Hello. Yes, I did profiling using Callgrind and OProfile and Linux is my main development platform. If the issue only appears when you change OS it may depend on OS configuration so let me test it on my workstation to see if I have the same issue before awarding me the project. I work full time, starting today. Close to your timezone. :)

Hello, I have done quite extensive profiling many times. I have good experience with valgrind's callgrind module. But all depends on what type of the program do you have, etc? So my questions are * what programming language your program is? * do you have source code for it? * is is platform independent? * do you run it the same way on Linux and Windows? Please share these important information with me, so that I can analyze and find the best solution. Best regards, George K
