[phenixbb] Discrepancy between Phenix GUI and command line for MR

[Xavier Brazzolotto]

Hi Randy,

Indeed I’m running Phenix on a brand new M2 Mac.
I will benchmark the two processes (GUI vs command line) and post them here.

Also, it’s possible the architecture matters so could you say which type of computer and operating system you’re using? If it’s a Mac, is it one with an Intel processor or an ARM (M1 or M2) processor? (By the way, we finally managed to track down and fix an issue that cause Phaser to run really slowly on an M1 or M2 Mac when using the version compiled for Intel, once I got my hands on a new Mac.)
