There are some more experiment that we can try, but the anomaly you
spotted should be healed now:
$ tune/speed -s 1000,3000,10000 -r mpn_sqrt mpn_root.2 mpn_sqrtrem
mpn_rootrem.2
overhead 0.000000002 secs, precision 10000 units of 2.86e-10 secs, CPU
freq 3500.08 MHz
mpn_sqrt mpn_root.2 mpn_sqrtrem mpn_rootrem.2
1000 #0.000051516 1.3866 1.4643 2.1827

You are welcome to test and/or give further suggestions
Best regards,
