As you've carefully provided all the info - I'll give the same bench mark a run on some of our systems here next week - and post the results. Obviously it's not an 'apples for apples' comparison - XenServer 6.5, from memory uses Xen 4.4. I think the OnApp system we're using Xen 3.4 If nothing else it'd be good to know we really don't have an issue rather than one we've not noticed (otherwise this might turn into a '/me too' post :) -Karl
