 Gocql has been tested in production against many different versions of Cassandra. Due to limits in our CI setup we only test against the latest 3 major releases, which coincide with the official support from the Apache project.
 
+NOTE: as of Cassandra 3.0 it requires Java 8, currently (06/02/2016) we can not install Java 8 in Travis to run the integration tests. To run on Casdnra >=3.0 enable protocol 4 and it should work fine, if not please report bugs.

+Performance
+-----------
+While the driver strives to be highly performant, there are cases where it is difficult to test and verify. The driver is built
+with maintainability and code readability in mind first and then performance and features, as such every now and then performance
+may degrade, if this occurs please report and issue and it will be looked at and remedied. The only time the driver copies data from
+its read buffer is when it Unmarshal's data into supplied types.
+
+Some tips for getting more performance from the driver:
+* Use the TokenAware policy
+* Use many goroutines when doing inserts, the driver is asynchronous but provides a synchronous api, it can execute many queries concurrently
+* Tune query page size
+* Reading data from the network to unmarshal will incur a large ammount of allocations, this can adversly affect the garbage collector, tune `GOGC`
+* Close iterators after use to recycle byte buffers
