Svn 1.9 repository 20% bigger than svn 1.8 repository

Hi.

I have a svn 1.9 repository, created with svnsync, that has ~150000
revisions and size about 45 GB. Due to some issues in svn-all-fast-export I
wanted to have svn 1.8 version repository so I downgraded it by doing
svnadmin (v 1.9) dump /svnadmin (v 1.8) load cycle. I was surprised that
the size of v 1.8 repository is "only" 37.5 GB
I tried to compare content of db\revs folder: some files are bigger in 1.8
repo, some in 1.9 repo.

Now I'm wondering:
1. Is such size increase expected for 1.9 repository? I read that 1.9 was
aimed at speed optimizations, but 20% size increase compared to 1.8 sounds
pretty big...
2. Or is my "dumped and reloaded 1.8" broken somehow? How could I verify?
(dump revisions one by one and compare? Or is there any better way?)
