That's great news. I guess it's client side caching kicking in here.

On a side note: The numbers suggest that the server side caching
apporach proposed in https://bugs.cacert.org/view.php?id=1001 at least
does not result in an OCSP load we could not handle (additional ~58
requests per minute but probably reduced load on the OCSP server due to
the other servers taking some loads) and therefore might be doable.
