Comment 18 for bug 1579580

not foundation team but looking at the issue
a) Difference is much smaller but difference between memory and SSD is still very large.
b) its only triggering a read/cache of files that would be read anyways. I have quite a bit starting up on boot and if I'm reading correctly there are 2400 file and they are mostly small executables and conf files.
c) As noted the cached list is smaller than 90k files

More importantly in the messages I see here and for me skimming my log the messages seem to mostly be '..' or a list of individual directories in the /sys filesystem. Its weird but not useful to judge what's being cached.
