Ok, so if you have large numbers of CPU's and large page sizes it's not
useful. however, what about a 2-4 cpu machine with 4k page sizes, 8-32G
of ram (a not unreasonable Opteron system config) that will be running
5,000-20,000 processes/threads?
Dont forget 'struct files_struct' are shared between threads of one process.
So may benefit from this 'special cache' only if you plan to run 20.000 processes.
I know people argue that programs that do such things are bad (and I
definantly agree that they aren't optimized), but the reality is that
some workloads are like that. if a machine is being built for such uses
configuring the kernel to better tolorate such use may be useful
If 20.000 process runs on a machine, I doubt the main problem of sysadmin is
about the 'struct files_struct' placement in memory :)
