Thank you for the interface.
On my computer, I have 134 sec vs 28 sec.
load("lapack") works well in command line
Maxima and in XMaxima. In wxMaxima,
lapack files are read for few seconds.
Then wxMaxima hangs:
the cell containing line load("lapack") is "active"
(there is a box around the bracket of the cell)
while Maxima process does nothing.
