Out of curiosity Stefan, if we had an alternate C-API with similar methods
(e.g. PyPyList_Append or so), but different signatures and memory model,
how hard do you think it would be to have Cython support this?

We cannot publish the benchmark that we used due to its usage of non
public data.
We'll prepare a benchmark which uses synthetic data, nevertheless it'll
have similar performance characteristics to the previous one, and we'll
provide it to you.
Many many thanks,
l.

I was able to fix the issue with scrapy.

Unfortunately, scrapy takes twice as long in PyPy than in CPython. I
suspect this is because lxml is twice as slow in PyPy vs CPython, which I
found in lxml's benchmarks.

Hi all,
I've been wondering whether the recipe that Raymond Hettinger posted
would also solve PyPy's performance problems with making huge
dictionaries:
http://code.activestate.com/recipes/578375/
The proposed layout makes the pointer-storing part of the dictionary
behave much more like a list.
