Subject JNA to avoid swap but physical memory increase
Date Fri, 15 Jul 2011 08:46:20 GMT
All:

I download JNA jar and put it to cassandra lib directory. When restart
cassandra server, I found the physical memory highly increase. There is
no data saved in cassandra, why so much memory used by cassandra? How
can I decrease the memory usage by cassandra? My version is 0.7.6-2.
