Re: [Scilab-users] Scilab 6.0.0, read()

[Lester Anderson]

Thanks Stefan for the script:

Windows 8.1 (64-bit) 4 Gb RAM

Program load time (approx)
5.5.2 ~9 seconds (with modules installed)
6.0.0 ~20 seconds (no modules)

5.5.2 results:
size(mat) = [1  7]
mat took 0.04 sec to read.
size(mat) = [1  7]

6.0.0 results:
size(mat) = [1  7]
mat took 13.62 sec to read.
size(mat) = [1  7

Cheers
Lester

Re: [Scilab-users] Scilab 6.0.0, read()

[Clément David]

Hi Stefan, Lester,

I confirmed the issue (0.02s in 5.5.2 vs 6.90 in 6.0.0) and on a local build I 
am able to trace the
issue using the Linux perf tool:

+   58,69%58,68%  libsciast.so.6.0.0  [.] 
types::getIndexesWithDims  
+   22,09%22,08%  libsciast.so.6.0.0  [.] 
types::ArrayOf::resize 
+   12,18%12,18%  libsciast.so.6.0.0  [.] 
types::getIndexWithDims
+4,04% 4,04%  libsciast.so.6.0.0  [.] 
types::ArrayOf::getIndexes 

So it seems that too much resizing occurs :/ . Could you post a bug with your 
test case please ? 

Thanks,

Here you are, Lester! A script that generates a comparatively small

Hi all,

Just a general query, but has anyone noticed that it takes a lot

Only installed a little while ago, but 5.5.2 loads really promptly on
a laptop with 4 Gb of RAM and a selection of modules starting, whereas
version 6 takes a while to get going (with no modules).

Haven't got as far as testing the functions, but just starting version
6 compared to 5.5.2 is slower; not sure what is going on. Testing on
Windows 8.1 (4 Gb RAM).

Do you have a test script to try, see if the issue can be reproduced?
