Hehehe
You forgot to mention these in your question:
if bla:
O.saveTmp()
O.loadTmp()
start_time = O.realtime
O.run(1000,True)
stop_time = O.realtime
So, you are not comparing loadTmp() vs. load(). You comparing loading
vs. NOT loading.
Comparing would need this:
if bla:
O.saveTmp()
O.loadTmp()
else:
O.save("bla.yade")
O.loadTmp("bla.yade")
Clearly, some internals are not saved with the simulation (e.g. the collider
has to regenerate itself), so loading introduces some initialization operations.
In addition, be careful, you are not comparing the same number of iterations in
your exemple above (1000 vs. 1100).
