[Scilab-users] Xcos 6.1.0 - benchmark time test

[Clément David]

Hello Pierre,

Are you using a block with its simulation function implemented in Scilab? Any C/C++ implemented block might perform the same at simulation time.

In 6.0.2, implementing Xcos blocks using the Scilab language had some performance issues. In 6.1.0, I tried to speed up things a little bit by reusing some allocated data structure during simulation time [1] ; more work might still be needed here.

Hello,

Here I test a PELTON basic algorithm under xcos, and record with tic-toc the simulation real time.
These programs have been set for 120 s (scope)

Results :
Xcos Scilab 5.5.2 :
Durée de la simulation : 45.4 s

Xcos Sciab 6.1.0 :
Durée de la simulation : 65.2 s

So the ratio is 1.44 for a basic sheme

Any explaination ?
Can that be improved ?

BR
