Thanks!
The performance is a bit disappointing though:

Any ideas? What kind of disks is ullmann running on? We were discussing SSDs at
some point, but I don't know what actually happened.
Don't get me wrong: the improvement compared to samosa is fantastic. But the
x2 factor compared to my laptop is a bit surprising. If we can tune it further,
now is probably a good time given it's not in production yet.
