The malloc.conf man page recommends U for security and F for debugging and it was that entry in the man page that inspired me to ask this question. Anyhow, thanks for taking the time to answer my somewhat naive questions, Theo and Otto. I will play around with the settings a bit, read the source and decide what I prefer. -- W. Steven Schneider

It depends what you want. If you want to use these features to dynamically discover software problems, you found a feature other systems don't have. Otherwise, don't create it.
malloc.conf recommended settings
Hi, I have a question about the recommended settings for /etc/malloc.conf. I'm currently using JUC on my i386 laptop, just to see how the old beast handles it. I hadn't noticed any significant performance issues though it did crash Chromium because it was using memory it had just freed. On my amd64 desktop I am just using J as I was working on some assignments and I didn't want to try anything too risky until I had completed the assignments. What are some recommended settings for /etc/malloc.conf in given scenarios such as general use desktop, or an internet facing webserver? Thanks. -- W. Steven Schneider
