[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) = [10000  7]
mat took 0.04 sec to read.
size(mat) = [10000  7]

6.0.0 results:
size(mat) = [10000  7]
mat took 13.62 sec to read.
size(mat) = [10000  7

Cheers
Lester
