Performance Issue

Hello,
I am usually used perl 5 on Centos system and I  recently installed a Rocky
Linux system. When I execute an important perl program on Centos 7 it is
very fast but the same program on Rocky Linux 8 is very slow. The server
hardware is similar (RAM / Speed disk, CPU ...)
Have you some ideas about this issue ?

Perl Version on Rocky Linux 8 is 5.26
Perl Version on Centos 7 is 5.16

Thanks
