hi,Nitin

This is the interbench data I did on LTSP, collected when :
* without any swap
* only local disk swap is on 
* only ramzswap 

I had planned to use the typically setup LTSP --- nbd-server/client as the swap,
but it seemed to be buggy, the machine halted doing interbench.

The data is as follows:

a) no swap
