Oh, and another known issue in darcs v1.0 is that the initial "get" (equivalent to a cvs "checkout") stores the entire history in RAM at one point. For example, I'm now doing a "darcs get" on the Linux kernel, and it is using 504 MB virtual... After I've finished this darcs get, I'll subsequently be able to do "darcs pulls" to update the kernel source while using only an amount of RAM proportional to the new patches that I'm getting.

Is that memory usage swap-friendly? If so, that's not so bad since 1GB of swap area is not too much (I have a lot more, as backstorage for tmpfs anyway, I assume many do the same on their development boxes)...
But still, it is quite non-scalable...
The Darcs Revision Control System Posted Nov 11, 2004 17:25 UTC (Thu) by larryr (guest, #4030) [Link] I think maybe it should be called "darcs beta 1.0" because there are several ways in which not only is it not really ready for widespread use, but it is not clear to me how it is going to get there. But I hope it will, because I prefer it to the way arch has been so far, and I tend to think there will only be one dominant patch-oriented open source solution. Larry

From his post to lkml announcing the darcs mirror of linux

The Darcs Revision Control System Posted Nov 12, 2004 18:37 UTC (Fri) by larryr (guest, #4030) [Link] I think the performance problems with darcs may be related to deriving metadata information at runtime rather than storing it explicitly in files or filenames; in other words the fundamental approach is resource intensive rather than the particular implementation.
