Hi, 1. GC tuning for cassandra is vital for cassandra performance, hence MB performance. 2. I am attaching an client I have written for testing MB. For readme go to bin folder and type
sh andesClient.sh man You can adjust speeds of messages/message sizes etc using this client. https://drive.google.com/a/wso2.com/file/d/0B57HoxWKqqNnSUctRXRZSTRyd0k/edit?usp=sharing Thanks On Mon, May 26, 2014 at 2:37 PM, Daya Attapattu <[email protected]> wrote: > Hi Hasitha, > > Thank you for the response. > > If you don't have benchmarks setup at the moment that is OK.
