well i tried by leaving the batch size as is (25) - server: localhost:9943, ip:9943, ....etc.  (for other devices) - processes: 2, 2, ....etc. (as much as the specified ip addresses in the "server" for core2duo devices)

but this seemingly doesn't work as i normally get only a single device (mostly the other than the workstation i am on) working on full CPU power

i don't really know what to do? ,, i have tried to increase the batch size .. but that seems irrelevant though.,,

Thanks in advance.
