Fixed In Version:		Doc Type:	Bug Fix
Doc Text:	Performance speed for Storage Pool Manager (SPM) tasks was reduced when the ISO domain was inactive and disconnected from the SPM. Now, VDSM computes the ISO prefix asynchronously, and does not wait for the ISO domain to report its prefix before executing SPM tasks, so the performance of SPM tasks remains constant.
