Hi Artem,
Regarding the benchmarks, we used self-implemented test with system calls load for now.
We used RedHawk Linux approach as a reference.

The "An Overview of Kernel Text Page Replication in RedHawk™ Linux® 6.3" article was used.
https://concurrent-rt.com/wp-content/uploads/2020/12/kernel-page-replication.pdf

The test is very simple:
All measured system calls have been invoked using syscall wrapper from glibc, e.g.

#include <sys/syscall.h>      /* Definition of SYS_* constants */
#include <unistd.h>
 
long syscall(long number, ...);

Thank you for the information on the tests. I will try this and get back with numbers.

Best Regards,
Shivank
