Subject: Unnecessarily writing .stored files that are already up-to-date
As shown by the log below (and confirmed against 0.048), CPANPLUS is writing the Storable datafiles every time they're loaded, regardless of whether any indexes are reloaded or not. IF (a) the indexes are loaded from .stored AND (b) the indexes are not modified in memory, there's no need to write them out on each exit. By not doing this extra write (especially on slow machines), CPANPLUS appears to be much faster. coral@cay:~/work/ > cpanp CPANPLUS::Shell::Default -- CPAN exploration and modules installation (v0.03) *** Please report bugs to <cpanplus-bugs@lists.sourceforge.net>. *** Using CPANPLUS::Backend v0.045.

yes, although thats true, its meant to be that way -- afaik it's kind of hard to see wether the structure has been modified in memory, and therefor knowing if you have to write the storable files to disk or not... of course there are ways, but none seem faster than just writing them... suggestions welcome of course -jos
