For some time now, top has refrained from updating the current number of cpus and memory totals with each and every refresh cycle. Rather, to lessen overhead costs, such values are updated periodically (5 min & 3 secs). The delay in updating the cpu count was only important with the addition of a cpu, since any loss is detected immediately. And the large interval was chosen because of the costs once associated with a glibc sysconf call and an unlikely scenario of physically adding the cpu. But the ease with which cpus can be taken offline then placed back online under linux suggests that 5 minutes may be too high. So, without addressing the likelihood of that act, top is now more responsive in these ways: 1) that 5 minute interval has been reduced to 1 minute 2) any key, not just Enter/Space, refreshes cpus & mem Note: we leave the man document as is, suggesting that only the Enter/Space keys force an update for hotplug.

COMPATIBILITY
This code is intended for use with Linux 2.6.xx, 3.x and
hopefully all future kernels.
INSTALLATION
If you are using git version of the project you need extra step.
./autogen.sh
After that, and everyone using .tar.xz version of procps-ng, can
do normal build. Read './configure --help' to select options for
your needs.
./configure
make
make install
If you have DejaGNU installed you can run optional test suite.
make check
HOW TO CONTRIBUTE
See Documentation/BUGS file.
PACKAGING
If you are a downstream maintainer (packager) for a Linux
distribution, please avoid causing troubles. This section
applies to you.
Avoid maintaining distribution specific patches. Send your
patches to upstream, where they are at least reviewed, if not
included.
Please forward bug reports. If your bug database is public and
busy enough to bother with, please make this known. Follow
Debian's lead in making the bug database easy to comment on via
email without need for an account.
For normal packages, ensure that you do not add debugging flags
to the CFLAGS variable.
