The closest paper I can find comparing performance would be this one (section 3.4 for performance): https://eprint.iacr.org/2016/1017.pdf

Check out the Open Quantum Systems implementation, they've got a suite incorporating a number of quantum resistant algorithms: https://github.com/open-quantum-safe/liboqs

They have the SIDH implementation you mentioned (https://github.com/open-quantum-safe/liboqs/blob/master/docs...), and a test harness for comparing performance.
