That might be due to the fact that with interactive use, there is always a
slowdown by default due to the label generation and the storing of
previous results:
python <<EOF | maxima
while True:
print 't2 : elapsed_run_time()*1000$'
print 't2-t1;'
print 't1: t2$'
EOF
(beware, this is hard to interrupt)
Robert Dodier once pointed out that
nolabels: true
improves this situation and that additionally (reaching in to lisp)
(defun add-lineinfo (x) x)
(almost?) completely eliminates the generic slowdown.
