More performance numbers


Anshul ran some more numbers to see the max throughput and latency that we have observed with CTP3. Here are some numbers to share.


Note that these are the max throughput numbers and latencies observed at those values. If you reduce the throughput, then latency goes down. For example, in the Read 2k, if the CPU are not maxed out , then you can get latencies of about 0.6 ms or so.

** With all 17 dual core clients ( hardware I have) the 3 quad core server’s  CPU was not saturated L . The numbers are at around 65% CPU utilization.


*** With the 17 dual core clients the 3 node server  CPU was not saturated. The numbers are at around 75% CPU utilization.


****In all 20K numbers the network was saturated.

    Sorry, I’m a new with Velocity and could not understand what is the difference between client and agent. Can you explain what they are and what kind of tasks they are solving.
