Always running DS job

If a DS job (sequence) is created with 'Wait for File' activity stage timeout set to 'Do not timeout', then isn't that a 'always running' job until it finds a file.In such case is it going to affect the system performance.

No, and you can easily measure job system impact using prstat, topas, glance, top, or any other monitoring tool. The wait-for-file API can be read about in the DS BASIC manual.

Yes, it will run until it finds a file or dies. There shouldn't be any hit to much other than your filesystem, which will be polled every... four seconds(?), I believe, for the file.

Which one is better option in terms of performance :
1. Polling through Cron and calling a DS job
2. Using 'Wait for File' activity to poll.
Thanks.

Option 2 will use less resources for the same polling period.
