Overall, Occlum has better performance over Gramine/Graphene-SGX on process creation and IPC.
run_*.sh are for runing Occlum/Graphene instances, respectively.
sgx_driver_conf.sh is to set the softlink of SGX in-kernel driver in /dev/sgx. This is only for Linux kernel 5.11.
You don't have to do this on kernel 5.13+.
Refer to Steps.md for detailed testing commands.
Expected results on SGX NUC machine.
