100MB is not particularly surprising.

I would also say that there is a serious bug with bzr 1.18 and 1.14
repos if you actually enable line-ending conversions. As such, I would
recommend going with bzr 2.0, and the --2a format.

The 15-minutes part is fairly surprising. I don't really know what BE is
doing at that point, though if it just doing something like 'status'
internally, it might be trying to sha1sum all 10k files. On the other
hand, if you have content filters active, that may also be playing a
role, and it is filtering + sha1summing all 10k files.


I'll note that just importing bzrlib and pyqt, etc, gets me to around
20-30MB of memory consumption.

So I would report a bug about bzr-explorer taking a long time to refresh
the view when adding lots of files.

However, I would recommend that you upgrade to the latest version first,
to make sure it hasn't already been fixed.

(Windows installers for 2.0.0 final have just been uploaded.)
