We are generally using the C++ operator new(), which AFAIK is just calling the standard libc malloc(). This replacement malloc() sounds very interesting. I've been a little suspicious for a while that Linux isn't particularly well-tuned for C++, and perhaps this can help. If you could give us a brief description of how you replaced malloc calls in your app with Doug Lea's malloc, that would be very helpful, in case there are any pitfalls we might not notice when trying it.
