> Key: CASSANDRA-15798
> URL: https://issues.apache.org/jira/browse/CASSANDRA-15798
> Project: Cassandra
> Issue Type: Bug
> Components: Messaging/Internode
> Reporter: Jordan West

> Priority: Normal
> Fix For: 4.0-beta
>
>
> The change to make dynamicBadnessThreshold volatile and mutable in
> https://issues.apache.org/jira/browse/CASSANDRA-12179 could have minor
> implications for the performance of this code:
> https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/locator/DynamicEndpointSnitch.java#L216.
> Its better to calculate this once before the loop starts, which has the
> added benefit that the value is stable throughout the calculation as well.
