> (I'm hoping to have time to run my test on EC2 tonight; will see.) Well, I needed three c1.xlarge EC2 instances running py_stress to even saturate more than one core on the c1.xlarge instance running a single cassandra node (at roughly 21k reqs/second)... Depending on how reliable vmstat/top is on EC2 to begin with.
Would have to revisit this later if I'm to get any sensible numbers that are even remotely trustworthy... -- / Peter Schuller
