Are there different distributions of Linux that perform better than others for this project or in general? Is there a difference in performance of Debian based OS's vs. Arch based? Are there certain settings/parameters you can change in the operating system that can improve performance/efficiency of crunching?

Are there also settings/parameters for windows that can be improved to speed things up?

Are you seeing the 3-day rb tasks with the "Computation error" status under Ubuntu 18.04? I've had a whole string of them, so I decided to visit the website and see if anyone else was reporting something along those lines... The normal deadline rb tasks seem to be okay, as are the various other tasks.

As regards performance variations among the various distros, I doubt there is much difference there. While I haven't tested between distros, the various distros are mostly using similar kernels. I do have one multi-boot machine that runs on Linux some of the time, and the performance on that machine seems pretty similar under completely different OSes. I have noticed some memory problems under Ubuntu on one machine, but I think that's a BOINC Manager problem, not a Linux thing.

I doubt their is any difference in Linux distributions. Rosetta is a statically linked CPU intensive app and they all should run about the same. My Fedora load is working fine.

Looks to me like a Rosetta problem that you should be able to work around.

All your jobs seem to be failing with the message "rosetta_4.07_x86_64-pc-linux-gnu: loadlocale.c:129: _nl_intern_locale_data: Assertion `cnt < (sizeof (_nl_value_type_LC_TIME) / sizeof (_nl_value_type_LC_TIME[0]))' failed."

The error message seems related to LC_TIME.

I Googled "loadlocale.c:129: _nl_intern_locale_data: Assertion" and there were several similar matches found. There are a couple that seem to be related to static linking and the default settings of the "locale" variables. Mine on my Fedora machine are below. Maybe that will help.
