Hello, Thanks to SOLR-12743 - one of our collections can't use FastLRUCache - we are considering LFUCache instead. But there is SOLR-3393 as well, claiming the current implementation is inefficient.
But ConcurrentLRUCache and ConcurrentLFUCache both use ConcurrentHashmap under the hood, the get() code is practically identical. So based on the code, i would think that, despite LFUCache being inefficient, it is neither slower nor faster than FastLRUCache for get(), right? Or am i missing something obvious here? Thanks, Markus https://issues.apache.org/jira/browse/SOLR-12743 https://issues.apache.org/jira/browse/SOLR-3393
