Did you pick the wrong link?

The different timings aren't between the jed version. I've made a test
between direct call of "()=up(1);()=down(1);" and go_{up,down}_1().

This is the point I'm interessted in: Is the memory gain of small helpers
greater or lesser than the speed gain? And
<slrnbh5etp.1l1.joerg@xxxxxxxxxxxx> shows, that go_{up,down}_1 takes two
time as much as ()={up,down}(1). So I would pick the up(), down(),
because it's easier to extend memory then get more cpu speed.

#v+
$ xjed -batch -n -f "evalfile(\"/tmp/test_test.sl\")"
go_ud_1: loop: 4.22, eval: 0.00
direct: loop: 2.76, eval: 0.00
$ jed -batch -n -f "evalfile(\"/tmp/test_test.sl\")"
go_ud_1: loop: 4.25, eval: 0.00
direct: loop: 2.78, eval: 0.00
