I haven't noticed performance degradation, but my jails aren't doing much. There are several providers selling jail-based virtual servers. I didn't consult the source, but my understanding is that a jail marks individual processes, so, e.g., if a jail runs just one process, that's the (operational, I don't know about startup) overhead for that jail. -- Ng Pheng Siong <ngps@netmemetic.com> http://firewall.rulemaker.net -+- Manage Your Firewall Rulebase Changes http://www.post1.com/home/ngps -+- Open Source Python Crypto & SSL
