Previously, only btree nodes were saved compressed and docs were not. I didn't realize the compression was so expensive, but now that I switch it off on both the branch and on trunk, I see big performance boosts for both.
And now the tail append stuff is slightly faster on my machine.

To clarify, disabling the compression completely on both trunk and the branch results in big performance increases for both, with the tail_header branch now being slightly faster than trunk running the lightning test on my
machine.

Awesome. Is there a noticeable size difference on the database files?

It looks to take about 2x as much diskspace as without compression.
