Subject Thrift CPU Usage
Date Mon, 26 Sep 2011 13:32:43 GMT
Hello - 

I have been running read tests on Cassandra using "stress" tool.  I have been noticing that
thrift seems to be taking lot of CPU over 70% when I look at the "CPU samples" report. Is
this normal?  

CPU usage seems to go down by 5 to 10% when I change the RPC from "sync" to "async".  Is this
normal? 

I am running Cassandra 0.8.4 on Cent OS 5.6 ( Kernel 2.6.18.238) and Oracle JVM. 

- 
Thanks
