Hello, This question is mainly directed to the developers. I am building an RPM package of NSD 2.3.7 for use on CentOS 4.5. I notice that one of the options available during the configure phase is "--enable-mmap". The release notes briefly mention it as being useful on Solaris, but don't talk about any other OS. Since it is not enabled by default, I'd like to ask whether there is any benefit to be had on enabling it on CentOS. -- Anand Buddhdev
