This may include some stuff that's only accessed a few times a year, but would otherwise be occupying precious RAM that would be much more useful as a disk cache. That said, FreeBSD tends not to page out except as a last resort - probably a mistake but I can't prove it.
Thanks, this is what I didn't know because I know it use to swap a lot, even if RAM was available (albeit, that may behave been v4...).
I think I'll leave it for now, the machine has 8 times as much RAM as the one it replaced and is doing less, so I really shouldn't have any issues. The previous machine was setup to use a swap file instead of a partition.
This is my signature. There are many like it, but this one is mine.
