Description
Some research projects use significant disk or other resources and concurrent start up of tasks can cause an impact on the system or possible result in heartbeat non-response. See http://www.worldcommunitygrid.org/forums/wcg/viewthread_thread,30688_offset,0#428458
It would be useful if the client would stagger the startup of tasks to avoid this issue or impact on the users machine.

What does BOINC report as the working set size of those jobs? How much RAM does the system have?
Note: See
TracTickets for help on using
tickets.
Would propose for the <start_delay> tag to also work when coming out of hibernation. Staggered starts would be ideal as a second control. Certainly have found that if 8 CEP2 start at the same time, there's at least an hour passing of disk trashing before even 1 second of CPU time is logged, if system is left alone. From user perspective impossible.
