Subject [jira] [Created] (CASSANDRA-11681) Pick a better file_cache_size_in_mb default

-------------------------------------------

             Summary: Pick a better file_cache_size_in_mb default
                 Key: CASSANDRA-11681
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-11681
             Project: Cassandra
          Issue Type: Improvement
          Components: Local Write-Read Paths
            Reporter: Branimir Lambov
            Priority: Minor


Currently we set aside at most 512MB, chunk cache of 480MB. We should probably go higher,
but we need to evaluate to what extent it makes sense to prefer chunk cache over compressed
OS page cache / row cache etc.

The size of the space reserved for pooled buffers outside the cache {{ChunkCache.RESERVED_POOL_SPACE_IN_MB}}
could also benefit from some tuning.
