It seems to me that the arena pause_time parameter must be tuned
together with the size(s) of the generation(s).  Smaller generations
require shorter pause_times.  I gravitate towards 10MB for the first
generation and 10 milliseconds pause time.  My feeling is that something
in the order of 10MB should work better than 100MB.  Of course, this
requires measurements to be sure.
