Concurrent tasks with vCloud 1.5.1 and vCenter 5.0

Hi guys,

I saw recently in the list of recent tasks of the vCenter which backs the vCloud Director 1.5.1, a number of "Suspend VM" tasks that delayed for 5-10 minutes all the other power on/deploy operations started by users.

For instance, when there are "Reconfigure virtual machine" operations, these are always done 1 by 1 with no concurrency.

I wonder if this is normal, or if there is some parameter to be changed in order to increase concurrency at the vCloud/vCenter level.

Thanks,
