      The use of entries such as the above have a minimal effect on the amount
      of RAM used, but a huge impact on processing time since each entry must
      be compared against each log record. If you have lots and lots of
      PageType/IndexAlias/Hide/Group/Ignore/Include/SearchEngine entries, they
      will have a large impact on processing time since each one must be
      processed for each log record, and the impact is linear depending on the
      number of such entries.

      Depends. Some just keep the match string in a linked list, so it only
      takes however many bytes required for the string + linkage. Others
      will also create a hash table entry of whatever size required for the
      object being referenced. The size depends on the object, since each
      object maintains different metrics particular to the object.
