Even I have the same confusion. From what I understand top command displays as a percentage of a single CPU. On multi-core systems, you can have percentages that are greater than 100% https://unix.stackexchange.com/questions/145247/understanding-cpu-while-running-top-command

  • This is not the answer to the question, he is asking about the reason of the difference between two results. – arashka Jul 26 '18 at 20:43

YourKit profiler treats entire CPU with all cores as 100%. It means that if you have 4 cores and 1 core is fully loaded and other 3 cores sleep, then CPU usage will be 25% (not 100%).

After this explanation YourKit results correlate good with "top".
