          Cache is used when 'use_uncompressed_cache' user setting turned on (off by default).
          Uncompressed cache is advantageous only for very short queries and in rare cases.
 
-         Note: uncompressed cache is pointless for lz4, because memory bandwidth is slower than multi-core decompression.
-         Enabling it will only make queries slower.
-         If number of CPU cores is in order of 100 and memory bandwidth is in range of 100-200 GB/sec,
-         there is a chance it is also being pointless for zstd.

+         Enabling it can sometimes paradoxically make queries slower.
