Increasing NR_CPUS seems to have a negligible effect. I see about a 1.1M
increase in memory usage when switching between 128 cpus and 5120 cpus. Since
most systems ship with 4G or more these days, I cannot see an issue with
consuming a small amount of memory like this.
The current NR_CPUS in Fedora is 128 and the current NR_CPUS in RHEL7 is 5120.
I do not see any reason that those values have to be different anymore.
I guess the question here is anyone aware of anyone running Fedora with
128 cpu's or for that matter 5120.
If the answer to that is no then there are only downsides of adding this...
