Windows Paging File Size
In Jade release 6.3 and earlier, the bulk of the database cache was kept in Windows file‑system cache, which is not backed by the pagefile.
From Jade 7.0 and later, the bulk of the database cache is kept in the database server's disk cache, which is backed by the pagefile, so the pagefile therefore needs to be large enough to hold it.
The recommendation is to let Windows manage the pagefile size, unless you have a good reason not to do so.
