In this case, I'd say around 30 seconds per request.  next time I'll  
time it more precisely.

I appreciate your efforts.  I suspect that this will help a little .

I'm certain that baking will help a lot. We just need to find someone  
with enough time to implement it.

Can you tell if the memory leak is coming from PyPI or from the  
Wiki?  I think that another short term thing to try would be to put  
PyPI on its own machine to protect it from Wiki load. I don't know if  
this will help, but it might be worth trying.
