I just found out that archiving and when "Setting Mode",  strip is only using 5% of 1 core no matter how many are free cores there are on the current Mac.  Strip is also not disk bound.
Just tried this across 3 Macs while archiving.  Apparently, strip is single threaded and takes tens of seconds stripping symbols from intermediate files while never going over 5% CPU utilization on one core.

If it’s not CPU-bound, and not I/O-bound, then what is it doing? Calling sleep()? Try using `sample` on it to see what it’s spending time in.
Only thing I can imagine is that it uses a ton of memory and your OS is swapping.
