I am trying to protect the SSD. That should work pretty well. However what's your swapinfo say? If you do happen to fill up RAM with your tmpfs, you'll end up swapping a bunch of memory pages out to the swap area, and if your swap is on the SSD, then you've pretty much defeated the object of the whole exercise. That aside, it looks good. If it's possible, adding noatime to the tmpfs mount flags will help with performance. Cheers, Matthew --=20 Dr Matthew J Seaman MA, D.Phil.
