Hello Alexander,
I've been trying to recompile Cantor for enable the debug possibilities,
but I did not succeed. I run into a GPG error that I can't solve.
So I apologize for this failure of mine.
Currently I'm using maxima-ecl 5.41.0-1 and sagemath 8.1-4.
One more time I want to thank for quick relies and support.

The connection to and the initialization of a backend process takes some time. The \
times are different for different backends.<br> Your observations about the long \
evaluation times for the first expression and almost instant evaluation of the \
subsequent expressions<br> is because of the recent improvement that was done in \

saved project files is much faster now and the initialization of the backend process \
is<br> postponed to the point when the user really asks Cantor to evaluate \
something.<br> <br>
The recommended versions for R and Sage are missing, yes. But those are minor issues \
compared to the crashes you have. Let's have a look at them first.<br> Which \
versions of Maxima and Sage are you using? Any chance to install the debuginfo \
package for Cantor and to try again? Without the debug symbols<br> the crash dumps \
are not really useful...<br> <br>
Connection to R is broken, the fix for this is "work in progress" at the \
moment.<br> <br>
