Hi, I don't know if it's relevant, but in January i have sent a message to the mailing list about this.

I put my changes here. https://github.com/softov/unbound This branch is 1 commit ahead, 12 commits behind NLnetLabs:master. But, if you need, I can make the update. > Depending on how invasive this is, I can put it in the mainline code > (optional) or it can be a patch that is available to other users in the > contrib directory. As I said before. This make 2 SHM instances and I am using the timer to stats-interval to fill the memory. I have some daemons, reading this stats with shmget each second. It's been a few weeks since I launched the last release with this changes for my clients. I have ~2400 clients running my SO, called FreeBRS - Free BrByte Routing System. Which is a release based on FreeBSD. For those clients, the average of requests are between 50 and 1500 per second. I all clientes, the CPU consume is 0%, while using my own daemon, who use ssl in a tcp connection like unbound-control. The CPU increase ~3% in my daemon and ~2,5% in unbound. -- -- -- -- -- -- -- -- -- -- -- -- > Although there may be an rc3 because of pkg-config vs autoconf problems, > I don't want to introduce features in rc3; so it'd be there for the > subsequent release. I thing there is more to do about, like. 1 - setting variables in conf (I don't know how) * shm-key: number * shm-enabled: yes or no Maybe * shm-interval: number, if 0 or null shm will be filled in the timer of stat-interval, like i have made, > 0 will be created a reserved timer and I don't know how to interact with the base or how much I can change because, you know using threads, this can create problems 2 - reset shared memory - zerofill values 3 - A header file.h to be referenced in the binary who is reading this info like a file with the struct and etc. For now, I only need the conf options, and I don't know how to make those. It will be my pleasure to help you in some way. The Unbound have been helping the community a lot. Here in Brazil, its used by about 80% of the ISPs. Thanks for the reply. Best regards, Softov
