I hate to deflate your ego, but you're dealing with a tiny amount of data, assuming a modern machine ( less than 5 years old ) equipped with modern main memory ( 256 MB? 512 MB? 1 GB? ).

25,000 records, at (pessimistically) 100 bytes per value, takes up 2.5 MB, or 1% or a small memory space.

Some people read multi-megabyte log files into a hash for post-processing. You should have no problems at all.

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
