Public bug reported:
The man page says:
The "-m" option controls how much memory par2 uses. It defaults to 16
MB unless you override it.
It doesn't say why one would want to control it, but a little
experimenting shows that this seems to be a space-time tradeoff. (Not
too surprising considering the algorithms involved.)
Given that par2create can take a very long time on gigabytes of data,
and given that 16MB is *really* small in 2010, when even cheapo netbooks
come with 1 or 2GB of RAM, and given that no one in their right mind
would be running par2create except on a reasonably powerful machine (so
several gigabytes of RAM), it seems to me that the default setting is a
tradeoff that made sense a decade or two ago but no longer, and should
be drastically increased. 128MB doesn't seem unreasonable to me. (Heck,
cellphones like the iPhone come with more RAM than that.)
