Note that you really need to uncomment the -XX:PrintGC* arguments to get a detailed GC log from the jvm before taking guesses at this; the numbers GCInspector can get are NOT pause times. High numbers for CMS are perfectly normal there, but in a healthy system they are Concurrent (the C in CMS) meaning Cassandra can continue running for almost all of it. -- Jonathan Ellis Project Chair, Apache Cassandra co-founder of Riptano, the source for professional Cassandra support http://riptano.com
