I have upgraded to 3.0.5. Now the time taken to run the factor script is down to 2s (with 3.0.3 it was 12s) I am trying to call Sage from a Java web application. So far the only way I know is to do it indirectly by running a sage script from Java. Is there a more directly way of calling Sage from Java ? The factor script is just a test. In general, my sage script would do different computation.
Thanks!
