I have found something that is perplexing me. In particular with Smartlist performance, I have see a drastic drop in performance when moving from a five year old Dual Processor Dual Core Dell PE 2950 with only 8GB of RAM and a RAID 1 and RAID 5 disk layout to a Virtual Environment with 16 virtual cores, 64GB's of RAM and utilizing a Compellent SSD disk backplane (datacenter grade). The old server produces Smartlist results 2.5 times faster than the new WMWare Virtual Server. I have seen this happen in more than one environment in two different companies who moved from physical to virtual when they upgraded to GP 2013. You see the same results with GP 2010 R2 before the upgrade to 2013.
Has anyone run into this drop in performance? Note, memory, processors and disk IO's barely get pegged on the new server when the Smartlist is producing results. Also, on the old server the results run at a consistent speed but on the new server the speed fluctuates.
