I just happened to have a close look at the memory usage figures on various -STABLE machines and noticed that all of them are reporting vm.stats.vm.v_wire_count roughly 1/3 of total RAM. (My look was triggered by the sound of my firewall paging when I sent a query to its named). Having 1/3 of memory wired strikes me as excessive - especially since none of the machines were particularly busy or doing anything that would be mlock()ing lots of memory. It was also consistent on 4 different machines having between 20MB and 512MB RAM and running versions between 4.5-STABLE and 4.7-STABLE, so it isn't an anomoly on a single machine. "vmstat -m" doesn't suggest anything (in fact it only accounts for about 15% of the wires pages). Can anyone explain why so much RAM is wired?
