Put; Using Put to save large lists of data is very slow.

I have data lists composed of many lists (say ~100k) where each list is ~20-30 items (always the same number); numbers, short strings, True/ False or Indeterminate. Saving this to disk (using Put) takes ~10minutes, reading it from disk (using Get) takes ~10seconds. Does anyone know why such a difference between reading and writing speeds exist? A factor of two would seem reasonable, not a factor of 60.
