Eric Evans commented on CASSANDRA-9766: --------------------------------------- I'm seeing something similar here; I get an eerily consistent 4.5MB/s _per stream_, (much less than the stream throughput limit, and the capability of the network). We have large partitions, large SSTables, and a mixture of 256k and 512k chunk lengths. [~yukim] what would be the best test of this, would https://gist.github.com/eevans/81f02849eab7634871c9 do? > Bootstrap outgoing streaming speeds are much slower than during repair > ---------------------------------------------------------------------- > > Key: CASSANDRA-9766 > URL: https://issues.apache.org/jira/browse/CASSANDRA-9766 > Project: Cassandra > Issue Type: Bug > Environment: Cassandra 2.1.2. more details in the pdf attached > Reporter: Alexei K > Fix For: 2.1.x > > Attachments: problem.pdf > > > I have a cluster in Amazon cloud , its described in detail in the attachment. > What I've noticed is that we during bootstrap we never go above 12MB/sec > transmission speeds and also those speeds flat line almost like we're hitting > some sort of a limit ( this remains true for other tests that I've ran) > however during the repair we see much higher,variable sending rates. I've > provided network charts in the attachment as well . Is there an explanation > for this? Is something wrong with my configuration, or is it a possible bug? -- This message was sent by Atlassian JIRA (v6.3.4#6332)
