[p4] How does Bitkeeper compare to Perforce?

[Tetlow, Gordon]

I just read through the page, while I haven't used bitkeeper so I cannot
comment on their featureset, some of the statements about Perforce are
either wrong or seen through the lens of someone that doesn't know
Perforce.

The 2 things that stand out as bald face lies are that Perforce doesn't
have atomic changesets and that merging in Perforce is primitive.

I especially like the part where using a database is considered a
negative. They also make it sound like all long running operations lock
out people (false).

A couple of other favorites:
The database can use a dramatic amount of disk space.
Upgrades are not reversible and lock the system for hours.

Both of these are true, although I'm not sure what 'dramatic' means. Of
course, with a little planning, neither are a problem. You should take a
checkpoint before upgrades anyway.

In short, this page is meant to scare people who don't know anything
about Perforce away from it. While there are a couple of items that are
true, most can be easily avoided with a little bit of forethought.
