Summary: Replicated cache performance degradation. Key: IGNITE-5293 URL: https://issues.apache.org/jira/browse/IGNITE-5293 Project: Ignite Issue Type: Bug Components: cache Reporter: Alexei Scherbakov With increase in number of nodes puts to replicated cache are slowed down almost in the same proportion.
