I do not understand few things: 1) Does JNA use JVM heap settings? 2) Do I need to decrease max heap size while using JNA? 3) How do I limit RAM allocated by JNA? 4) Where can I see / monitor row cache size? 5) I've configured JNA just for test on my dev computer and so far I've noticed serious performance issues (high cpu usage on heavy write load), so I must be doing something wrong.... I've just copied JNA jars into Cassandra/lib, without installing any native libs. This should not work at all, right? Thanks, Maciej
