We have batch jobs that were running fine without any issue for a long time. From last week onwards we are seeing that the jobs are long running. Our's is a sas environment hosted on linux machine. We have not made any changes to the code recently. The only thing i can see within the logs is that the real time of the procedure or data step has increased. We have checked wih Unix admins and they have told that no other process is running on the server. We have also run the jobs at different times to see if its a timing isue. But did not get any difference. Only thing we can notice is high i/o utilization on sas work library mount which was not there previously. Have anyone faced this issue or guide me on what to check further to imprve the performance
