even cancelling the operation has biblic times
it's half an hour right now since i pressed the cancel button
"please wait while the process is cancelled"
Yes, exporting the results of such a job run could be a little time consuming especially since you have 4000+ rules. And canceling the operation also is time consuming.
I would recommend not to cancel and wait it out for it to export the next time. If you cancel by any chance, a good way to bail out would be to figure the appropriate java thread and kill it manually.
i did precisely that
anywhay manually browsing the rules on the job output requires far less time than exporting them
