To achieve higher performance, you could try prioritising minecraft. To do this, open Windows Task Manager when minecraft is open. Right-click on it and select 'Go to process' at the bottom of the drop-down menu. Then right-click on the highlighted process (javaw.exe) and go to 'set priority'. Then click 'high'. I don't know about the lack of orcs, are you on peaceful mode?
