   That's highly unusual. Do you observer the same poor scaling every run? Are each of the tests running for at least 10 seconds?

   Yes, I observe the same poor scaling every run (around 4-5 runs) and also each of the tests running for at least 10 second. My CPU is AMD Ryzen 5800H

   Ok. I found that parser-125k is normal when I run on Ubantu in VirtualBox.
   I ran "make TARGET=linux64 certify-all XCMD='-c16'" in both Cygwin and Ubantu.
   I can't run "make TARGET=cygwin certify-all XCMD='-c16'" because there is an error "cygwin.mak : No such file or directory".

   Glad you solved the problem in Ubuntu. But running under a VM is not a good idea as you are subject to pre-emption at a higher level by the host OS.

   How were you able to run under cygwin in your first comment, but cannot run under it now?
