Excellent news. How many buckets with custom settings did you create?

For those interested, I identified my performance problem.

I was creating a lot of buckets, and the properties did not match the
default bucket properties of the node.  So getting the bucket was taking
between 300-400 milliseconds instead of 3-4.  Apparently creating buckets
with non default bucket properties is not just a bad idea, but a REALLY bad
idea.

I changed the default to be what I wanted for most of my buckets
(allow_mult=true) and tweaked the code to handle siblings where I wasn't
before, and now I'm getting lots of operations per second.

Thanks the for help every one!

One thing I am doing different than the benchmark is creating a lot of
buckets…

The objects are either tweet jsons, so between 1-2k, or simple strings with
some links.

I am using secondary indexes with timestamps so I can do range queries.
 Would this significantly impact performance?  I am not indexing for
search...

Here are some more bench results.  Obviously using the azure load balancer
is a bad idea.  Fortunately I'm not.

This was run from my laptop using 8 concurrent connections and the pb
client, using the load balancer in azure.  Lots of errors.

this was run on a vm in the same cloud service using 8 concurrent workers
and the pb client, but clustered directly (i input all the IP addresses
to riakc_pb_ips).  Much better ops.  So it must be something with my usage
that isn't getting captured by the benchmark.

What is the average size of one of your objects? Are you indexing?
