The ZODB small one doesn't, since instead of loading a dictionary, it loads an index into a dictionary (I think). The big Cremona database *does* take a couple of seconds on first load, since its index is really big (I think). Fortunately, Andrew Ohana rewrote it recently to instead use sqlite, and now it also loads instantly. I would very much *not* like it if the first time I run factor it always pauses for a few seconds to load a file. A way around that, might be to only load the file if the number to factor is at least 60 digits (say). Maybe the patch already does that? I didn't look. -- william -- To post to this group, send an email to [email protected] To unsubscribe from this group, send an email to [email protected] For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
