Comment (by jpflori):

 Running make ptest on a quite recent computer (12 threads), makes the
 runtime go from about 399 seconds on vanilla 5.3.beta2 to about 407
 seconds on 5.3.beta2 + #715 + #11521 + #12313 averaging on a few runs.

 On sage/schemes/elliptic_curves/sha_tate.py alone with long tests it goes
 from about 79 secs to about 82.5 secs.
