> In our Syncope installation (1.1.3 on Tomcat/MySQL) we observed long execution times
(>1s) for TaskDAO.findToExec(), which is called periodically from NotificationJob to determine
which notifications should be sent.
> According to our analysis, this is due to the fact that TaskDAO.findToExec() performs
a full scan on all entries of the task table with DTYPE="NotificationTask" (which could be
a large number as all executed tasks are kept), although only very few tasks are selected
(those with executed=0).
> Creating an index on task.executed solved this problem; attached is a corresponding patch
against the branch 1.1.X.
