I am finding that writes to the ZODB are far slower when the storage is BerkeleyDB instead of Data.fs. I should also mention that I run this through ZEO, if that has anything to do with it. I now have quite a few folders, some with up to 1000 objects in them. I know ZEO is not very write friendly, but if I switch the Storage back to main .. i.e. Data.fs(Still as a zeo client), and import data into it, then I find it is 5-10 times faster when doing something as simple as editing small dtml method.
