The speed of the array rebuild continued at a snails pace of a few GiB per hour. Given the array is 12 TiB, this was a big problem. Hat’s off to a comment by “Grizzly” in the forum as the recommendation to disable quotas did the trick. It took about a minute to complete its execution, but now the CPU usage of the 4vCPU VM have returned to normal operation sharing a total CPU load of about 25% equally between all processors accompanied by disk read and write stats consistent with the LSI SAS2008 MB controller. At the new rate, should take about 5 hours to finish the “delete missing” command.
