Thanks. For my own future reference, do you have a suggestion for a file size that is too large to use with Tie::File?

    Hm. Say 1000 lines/100kB.

    Its actually not too bad for files ~10x that iff you know

    1. how it works:

      An LRU cache of limited size:

    2. what not to do:

      Don't use @theArray in either a list or scalar context;

    3. configure it correctly:

      The memory and dw_size options can interact in interesting but unintuitive ways.

      Bigger is not always better, especially if the predominant operations are deletion or insertion of whole lines, rather than in-place modification of existing lines.

    With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
