nedmalloc

I am currently evaluating a few of scalable memory allocators, namely nedmalloc and ptmalloc (both built on top of dlmalloc), as a replacement for default malloc / new because of significant contention seen in multithreaded environment. Their published performance seems to be good, however I would like to check what are experiences of other people who have really used them.

Were your performance goals satisfied?
Did you experience any unexpected or hard to solve issues (like heap corruption)?
If you have tried both ptmaalloc and nedmalloc, which of the two would you recommend? Why (ease of use, performance)?
