Subject important performance note
Date Fri, 23 Oct 2009 03:21:40 GMT
Brandon Williams has been doing some testing on the garbage collector
options we are using, and found that removing the line

        -XX:CMSInitiatingOccupancyFraction=1 \

from bin/cassandra.in.sh dramatically increases throughput by reducing
the amount of CPU used by the garbage collector.

This will be part of 0.4.2 and 0.5, but in the meantime, thought you'd
like to know.
