tor/changes/ticket28838

  o Minor features (performance):
    - Remove about 96% of the work from the function that we run at
      startup to test our curve25519_basepoint implementation.  Since
      this function has yet to find an actual failure, we'll only
      run it for 8 iterations instead of 200. Based on our profile
      information, this change should save around 8% of our startup
      time on typical desktops, and may have a similar effect on
      other platforms.  Closes ticket 28838.
Lower the loop_max constant in curve25519_basepoint_spot_check() The point of this function is to make sure that the ed25519-based implementation of curve25519_basepoint() actually works when we start tor, and use the regular fallback implementation if it doesn't. But it accounts for 9% of our startup time in the case when we have directory information, and I think it's safe to make the test shorter. After all, it has yet to find any actual bugs in curved25519_scalarmult_basepoint_donna() on any platforms. Closes ticket 28838. 2018-12-13 17:26:09 +01:00			`o Minor features (performance):`
