NAME

       Cache::Ref::CAR - CLOCK with Adaptive Replacement

SYNOPSIS

           my $c = Cache::Ref::CAR->new(
               size => $n,
           );

DESCRIPTION

       This algorithm is an implementation of
       http://www.almaden.ibm.com/cs/people/dmodha/clockfast.pdf.

       See also Cache::Ref::CART which is probably more appropriate for random access work loads.

       CAR balances between an MFU like policy and an MRU like policy, automatically tuning
       itself as the workload varies.

ATTRIBUTES

       size
           The size of the live entries.

           Note that the cache also remembers this many expired keys, and keeps some metadata
           about those keys, so for memory usage the overhead is probably around double what
           Cache::Ref::LRU requires.
