Follow-up Comment #1, bug #56752 (project octave):
To check whether it is the execution of loops versus the execution of
statements in the body of loops, I ran the following empty loop body test.
a = 1; b = 1; tic; for i=1:1000; for j=1:1000; ; end; end; toc
The script is attached as bm.empty_loop.m
Results were
Version 3.2.4 3.4.3 3.6.4 3.8.2 4.0.3 4.2.1 4.4.1
5.1.0 dev (6.1.0)
0.053467 0.0782108 0.0723422 0.128019
0.1248 0.096776
There was a small decline in performance. However, 50 milliseconds is no
where near as important as the 7 seconds seen in the toeplitz benchmark which
included assignments, function calls, etc.
