Summary
As with any performance optimizations, your mileage may vary. We have covered
suggestions for how to get performance improvements up and down the stack from
the hardware layer all the way up to the Cassandra application and a few things
in between. As is common to most bits of advice, you'll have to test things out
and see what works for you. There are many additional options for tuning the Java
Virtual Machine for your workload.
Determining a specific configuration or set of configuration parameters that
works for you will make a large difference in the long run. It's also a good idea to
always keep an eye out for best practices and to learn from people who run similar
configurations or have similar requirements. There isn't always one right answer,
and getting the most out of your Cassandra cluster will require some testing. Start
applying some of the ideas discussed in this chapter to your cluster piecemeal and
watch for improvements. Always ensure that you have a proper baseline of per-
formance before making a change. The more you learn about how your cluster
performs under load, the more you will be able to optimize its performance.
