Why are the highlighted lines showing different flags (F6, F2, F4)? does this mean that there are differences between the three speed operations?
The manual explains the -mr option as: "Produce the summary in a mechanical, machine-readable, format." What's not clear is what reads that format. It turns out the format is designed to be read by the do_mulit function that implements the -multi option. That function reads the output of multiple parallel processes and uses the "+F" prefix to determine which algorithm was tested.
So +F4 is for ecdsa results, +F2 is for rsa results and +F6 is for eddsa results. Other than that, I don't think the actual F numbers have any significance.
