Comment 15 for bug 116094

Here are the 2.0.0 performance figures on an import of FireFox 3.5 on 2a format. The tree is large (40k files) and the repository is relatively shallow (19k revisions).

1. cp -a takes 59.7 seconds
2. bzr branch takes 4m43secs

By way of comparison:

3. 'hg clone --pull' (no hardlinks) takes 2m1sec
4. 'hg clone' (hardlinks by default) takes 52.4 secs.

So the apples-to-apples comparison (2 vs 3) implies bzr is still more than 100% slower than hg on this particular operation. That's clearly much better than the original 60X slower so I understand the desire to say this is now fixed. OTOH, it's likely users will simply re-open it as long as the gap is over 50%.
