Attention

C programs are not the same to Rust programs. Comparing the performance between Rust and C directly is meaningless. The only meaningful measurement is the slowdown of porting.

Note: The results are shown in the following are from single time running.

create_enclave and destroy_enclave perfromance test result

Rust-SGX create enclave average time = 0.002683090276s, var = 0.0000001723163121 (average needs to minus 60ns for time measurement) C-SGX create enclave average time = 0.002541857303s, var = 0.0000005211093912

Rust-SGX destroy enclave average time = 0.0001088015614, var = 0.00000000116750652 (average needs to minus 60ns for time measurement) C-SGX destroy enclave average time = 0.0001058573786, var = 0.000000001800703517

create enclave performance overhead = (0.002683090276 - 0.00000006) / 0.002541857303 = 5.55% destroy enclave performance overhead = (0.0001088015614 - 0.00000006) / 0.0001058573786 = 2.72%
