When using sendfile() on an amd64 box, are sfbufs still used/needed? The reason I ask: # netstat -m 0/0/0 sfbufs in use (current/peak/max) 0 requests for sfbufs denied 0 requests for sfbufs delayed 1334122 requests for I/O initiated by sendfile kern.ipc.nsfbufsused: 0 kern.ipc.nsfbufspeak: 0 kern.ipc.nsfbufs: 0 Does sendfile work differently on amd64 so that sfbufs aren't needed, or is this a statistics issue? This is in 7.0-RELEASE, btw. -- Kevin
