> Characterize the performance of 2.1
> -----------------------------------

> Key: USERGRID-772
> URL: https://issues.apache.org/jira/browse/USERGRID-772
> Project: Usergrid
> Issue Type: Story
> Reporter: Jeffrey
> Priority: Critical
> Fix For: 2.1.0
>
>
> We need to characterize the performance of 2.1. This will involve using:
> - Varying numbers of tomcats
> -- we can start with 20 and progressively add more into a load balancer to
> see the performance impact
> - Varying ES cluster size - starting with 6 and going up to 20
> -- we can start with 20 nodes and only have the indexes targeted to a subset
> - Varying ES bucket/shard counts - starting with 10
> - Varying Cassandra sizes - starting with 6 and going up to 12
> General approach should be:
> 1) Start with 2 tomcats, 6 ES and 6 C*
> 2) Add +2 Tomcats iteratively until the performance starts to not increase
> (implying that either ES or C* is the limiting factor)
> 3) Add +3 ES nodes and test again. Document impact.
> 4) Add +3 C* nodes, remove -3 ES nodes and test again. Document impact.
> 5) Add +3 C* nodes and +3 ES nodes and test again. Document impact.
> 6) Add +2 Tomcats and see the slope of the TPS graph
> 7) Add +3 C* - (now at 12) and test again
> 8) Test iteratively with +2 Tomcats until performance plateaus, up to 20
> Tomcats
