bzr pull takes significant amount of time for svn branch

[Philip Peitsch]

My bzr branch of an svn trunk with 11000 commits (33119 revisions in the whole of svn) is taking roughly 1m20s to perform a bzr pull operation:

Using saved parent location: svn+ssh://host.com/var/lib/svn/project/trunk
No revisions to pull.

Do you perhaps have a large number of tags in this repo?

The attached file isn't particularly useful, can you perhaps run with "--lsprof --lsprof-file pull.callgrind" (without the .out)?
