Hello,
I am currently porting a Scilab package (Sysmetab, on the Scilab
forge but not yet Atoms packaged) and I have noticed that Scilab 6 is
two times slower than Scilab 5.5.2. The involved computations are
very diverse but are vectorized products of submatrices, sparse
matrix algebra and sparse linear systems solving. Until now, I did
not have time to make a precise profiling, but knowing in advance
which type of operations/computations have eventually regressed could
be of great help to identify the bottlenecks...
bench_run() is designed for that:
https://help.scilab.org/docs/5.5.2/en_US/bench_run.html
On the same computer, you may run it on 5.5.2 for chosen modules, run
it as well on 6.0, and compare results.
This looks like finding a needle in a haystack...
