I spent 2 hours this week trying to figure out why, on one machine it (Ape-1.0) worked fine, 
and on the other it died with an assertion error. Yet the directory contents were identical, the 
python version the same, all the configs the same.

I eventually figured out how to solve the problem by putting an explicit 
mapper_name=python_script in many "effected" .xyz..properties files.

Though, figuring out which one was causing the problem was darn tough!

Otherwise it works fine. I don't have any opinion on performance though.

Isn't that a generic ZODB question, not really specific to Ape.. ?

I imagine the loading process is slightly slower than traditional ZODB, but I have not 
measured it. In our case, we're using it on a site that's all XML and XSLT generation, so 
there aren't  more  than 100 or so objects in Ape storage anyway.

No problems.
