|so indeed much slower for 1.9.2 than 1.9.1...wonder why...

It's not caused by float operations, nor multi core support, but
caused by time calculation.  We have relaxed time limitation in 1.9.2,
so that we would have 2038 problem no longer.  But it is slower than
previous.  Probably we need to tune up time routines.
