Note that 10 is a very small number of bytes per object. It's a key benefit of the ATS cache vs e.g. Squid cache (which consumes 60 or so bytes, last I checked). Nginx doesn't have this, since it just creates a file on disk (but imagine having 1 billion i-nodes on the disk, good times doing a full fsck on that ;).
Not to go into details, but obviously the kernel consumes memory for this type of disk cache (the i-node cache).
