Your definition of "reasonably fast" doesn't match mine. The number for SIDH (key exchange, when the thread was going off on a tangent about signatures) is ~200ms.
A portable newhope (Ring-LWE) implementation[0] on my laptop can do one side of the exchange in ~190 usec. Saving a few cells is not a good reason to use a key exchange mechanism that is 1000x slower (NTRUEncrypt is also fast enough to be competitive).
I have yet to see any SIDH benchmarks either. I checked the citation but I wasn't able to confirm where the ~200ms number came from. Thanks for throwing out specific numbers on Ring-LWE, I wasn't aware that it was so fast.
