I have imported 2 of the 7 repos - each import takes 5-6 hours :(
In total I now have 340k patches and I think roughly the same number of
comments. On my laptop, the db queries to display the list page takes a
terrifying 12 seconds, so I have no idea how kernel.org's lkml pw is so
fast. (It has almost a million patches!)
I then tried to apply the patches but they no longer apply to master. So
I pulled out a branch where I had applied some before, applied the
remainder, and rebased that.
I then ran 'time python3 manage.py migrate'.
The migration took 6 and a half minutes on my laptop and nothing was
oomkilled. So even for people with significantly more patches, the
migration should be doable.

(you'll have to add that manually as the patch isn't showing up in pw)
> I'll stick the URL patch on my review queue for sometime this week.
