Gonna try Mikhail suggestion, but just for fun you can also empirically "test" for how much of a file is in the oshr...@matrix.co.il cache with: time cat <file> > /dev/null

Note that running the command by itself encourages to cache the file. On Sep 25, 2015 12:39, "Aman Tandon" <amantandon...@gmail.com> wrote: > Awesome thank you Mikhail.
