My assumption is that the data comes initially from text; a file or other external source.

Thus, despite that it is numeric data, when split to an array, each SV in the array is an SvPV with the numbers stored as ascii strings.

But, if he runs over the array forcing the ascii to be stored in the IV or NV slot, then when Storable packs it, it only packs the IV/NV and not the PV, and so the Storeable image size is reduced.

Of course, if the size of the transmission is really significant, then transmitting the original source text would probably be more efficient. Especially if he zipped it first.


Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

In the absence of evidence, opinion is indistinguishable from prejudice.
