Hi Mohammed, QE version 6.1 contains many changes I made to the EXX implementation in order to improve the performance of the code when running large calculations on many nodes. The calculation you are running is very small and won't necessarily benefit much from these changes, but it certainly shouldn't perform worse. If you send me your input file and pseudos, I'll see if I can determine what is going on.
