One again: that speed-down is the effect of the disk operations which are
slower than in-core arithmetics in the ORDERS of magnitude. When you run
any external program from the disk those operations are _always_ included.
My point was: since any real script executes at least several external
programs the total time it runs will not be affected with the substitution
of 32-bit arithmetucs to 64-bit one, even when overflow checks are enabled.
I am not concerning about the speed of the external application running,
for I am solving the absolutely different problem now.
