[snip] It is significant specially doing **exactly** what you are doing
64: a large footy field 32: a small room with lots of drawers, You can only open 1 draw at a time: usual big mem scene: open a drawer and do lots of work, open another ... ltsp: open a drawer, do a little work, close the drawer, open another drawer ... The more work you do, as opposed to doing hard work, the more you need 64. In your case while you are 'opening the drawer' and 'closing the drawer' the work is piling up (Load Avg up). Open and close are non trivial so if you do it too often ... and you have 8 CPUs all waiting in line for their own drawer ...
