Hi, I have run cassandra-stress write and cassandra-stress read on my office PC and on my home PC.
Office PC : Intel Core i7-4479, 8 virtual core, 16G RAM, 500G SSD Home PC : Intel Xeon E3-1230V3, 8 virtual core, 8G RAM, 500G SATA disk. From the cassandra-stress result (please see below), it seems Cassandra ismore than 100% performant on my home PC than the office PC. I am expecting the other way around, as my office PC has much better hardware.

Thanks in advance for any suggestions ! Shing
