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.) ** Affects: par2cmdline (Ubuntu) Importance: Undecided Status: New -- par2create should use more memory https://bugs.launchpad.net/bugs/535305 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
