      Description

      After setting up the group choice activity with 256 groups, every try to use the group choice or to change it's settings caused a pretty high database load. With few users it only slows down the system but in our case of many users the whole moodle instance became unreachable.

      The log files indicate that the module code is not efficient (more database accesses than necessary). We experienced this effect of a massive slow down already with about 50 groups in the group choice.

      Because this specific activity is meant as an organisation tool for offline groups we use now the "Choice" Acitivity which works perfectly and fast!
