Thanks Phyllis; I finally saw some difference:

AppImage (no patch)

render exr to exr:                   176 sec, 19.491 fps
render exr +plugin to exr:      183 sec, 18.717 fps


Build (patch)

render exr to exr:                   172 sec, 19.970 fps
render exr +plugin to exr:      173 sec, 19.8 fps

Not sure you are actually using Exr Sequence for the whole Project instead of 1 single frame ?  Or maybe Arch just handles things much differently.  Because there is not much variation on the speedup shown in your results.  For a 1 1/2 minute video, this is what I am getting:
