Subject Re: [Cassandra] [Generation of SStableLoader slow]
Date Wed, 24 Dec 2014 12:40:48 GMT
I think that'd be slow copying large files with just the cp command.
Cassandra isn't doing anything amazingly strange here, you don't have a lot
of RAM, nor CPU and I'm assuming the underlying disk is slow here as well.
Without more parameters and details it's hard to define if there is an
issue.
