Sample code from post #49 in the forums further demonstrating decreased
performance
This was from post #49 as visible here:
https://forums.opensuse.org/english/other-forums/development/programming-scr...
Also saw a large slowdown on comparable systems when running on 12.3 vs. 12.2.
Using libm.so.6 from 12.2 x86_64 on the 12.3 x86_64 system increased
performance by several times as demonstrated below (using this code):
ab@mybox:/tmp> time ./a.out
x = 875.574
real 0m36.207s
user 0m36.145s
sys 0m0.001s
ab@mybox:/tmp> time LD_PRELOAD=/tmp/libm-from-12.2.so.6 ./a.out
x = 875.574
real 0m13.249s
user 0m13.226s
sys 0m0.001s
