Currently I am running 1 task at a time & they take 1 minute 20 seconds. (80 seconds) Running my card at 320 W I have some tasks that will run for over 100 seconds, don't know why this happens it appears not to be confined to me

I am wondering is running more than 1 task at a time beneficial, especially with the strain the server is having at present?

Thank you appreciate any feedback

On Windows you should be doing 2 or 3 concurrent with that GPU for max PPD, but on Linux I'm not sure as I don't have many Linux machines.

Thanks for the feedback. However I believe running 1 task is a faster running to tasks at a time takes around 3 minutes 22 seconds each giving 3,779.777 per minute total runtime of around 7.2 minutes however running 1 task at 1 minutes 20 seconds gives credit per minute of 10,279.69 so I get almost 3 times the amount credit running 1 task at a time.

If I have done my calculations wrong please feel free to correct me. A reminder I am running my card at 320 watt

Adding
Credit I get per hour doing 1 task at a time is 615,240
Credit I get per hour doing 2 task at a time is 225,861.44

Yes, in this case 1 concurrent is best. Never know until you try.
