Before commit 3cec5c77d617 buf_daemon() went to longer 1s sleep if numdirtybuffers <= lodirtybuffers. After that commit new condition !BIT_EMPTY(BUF_DOMAINS, &bdlodirty) got opposite -- true when one or more more domains is above lodirtybuffers. As result, on freshly booted system with no dirty buffers buf_daemon() wakes up 10 times per second and probably only 1 time per second when there is actual work to do.

This is the top level of the FreeBSD source directory.
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
