Hello Ilyas, I’ve got a few questions for you to help diagnose the
performance problem.
Hi and thank you for the answer
* What Riak version are you running?
2.1.1 from debian package
* Are you using the default solrconfig on the index, or a custom
configuration?
default solrconfig
* You say that there is a 200x slow down when Yokozuna indexing is
enabled. Do you have any specific numbers? A graph would be helpful if
you can generate one.
about 50 put operations per second to bucket with solr indexes, about
1000 put operations per second to bucket without indexes
* When you say that Yokozuna takes up 100% of one core, have you been
able to narrow that down to specific process within Yokozuna or Riak?
Using “riak-admin top” might help here.
