We have same problemes here. Cocoon1 is very slow, but stable. 
We are no more working with it because of the lack of sitemap (sitemap
is a great idea).

C2 is using amazing quantity of memory, go to the status page, each time
you reload it, C2 is using about 1 Mbytes of memory (a <map:read /> for
image, and a <map:generate type="status"/>, <map:transform type="xslt"/>
and <map:serialize type="html"/>).
Reloading a page like documents/developing/avalon.html is costing
like 9 Mbytes.

Under heavy load, we have stability problems. Sometimes, connection are 
accepted, but nothing is going out of the pipe (TidyGenerator reading
files, XMLSerialiser, 10000+ files). Servlet threads are exhausted and
we have to 
restart C2.

Most of the time, error reporting is not helpful.

Despite this, do not misunderstand me, C2 is great, I put it everywhere.
