OK, so can anyone tell the actual, current limits ?


Without CONFIG_HIGHMEM64G=y you have:
32 swapfiles, max swapfile size of 64GB.

With CONFIG_HIGHMEM64G=y you have:
32 swapfiles, max swapfile size of 512GB.

Does this apply to mmap as well? I have an application which currently uses 9TB of data, and one thought to boost performance was to mmap the data. Unfortunately, I know 16TB isn't going to be enough for more than a few more years :-(
