I fired up the Performance Monitor and noticed that the % Usage on the 4GB pagefile fluctuates between 4-10% while the computer is sitting "idle." (I calculate that to be approx. ~160-400MB.) Memory usage is sitting steady around 8GB.
The system has 64GB of RAM, and the pagefile resides on a 1TB SSD.
None of this is terribly confusing.
What is confusing is that there is zero write I/O going to the pagefile even as the % Usage continues to fluctuate.
In the last hour, % Usage has gone from a minimum of 4.1% to maximum of 9.7%, now sitting at 5.6%. Yet the total of Page Writes/sec as shown by Performance Monitor, as well as bytes written to pagefile.sys as reported by Resource Monitor, both remain at zero for the last hour (0 page writes, 0 bytes written.)
How is this possible?
