This was a problem pre vnodes. I had several JIRA for that but some of them were voted down saying the performance will improve with vnodes. The main problem is that it streams one sstable at a time and not in parallel.
Jira 4784 can speed up the bootstrap performance. You can also do a zero copy and not touch the caches of the nodes which are contributing in the build. https://issues.apache.org/jira/browse/CASSANDRA-4663 https://issues.apache.org/jira/browse/CASSANDRA-4784 On Tue, Jul 2, 2013 at 7:35 AM, Mike Heffner <m...@librato.com> wrote: > > On Mon, Jul 1, 2013 at 10:06 PM, Mike Heffner <m...@librato.com> wrote: > >> >> The only changes we've made to the config (aside from dirs/hosts) are: >> > > Forgot to include we've changed this as well: > > -partitioner: org.apache.cassandra.dht.Murmur3Partitioner > +partitioner: org.apache.cassandra.dht.RandomPartitioner > > > Cheers, > > Mike > -- > > Mike Heffner <m...@librato.com> > Librato, Inc. > >
