> Currently, as the number of profiles increase, we reload the same list of profiles from
the FS.
> An ideal improvement would be to detect if there are any new profiles and only reload
from the disk then. Otherwise, a cached list is sufficient.
> For a directory of 280K profiles, the load time is close to 6 seconds on a 32 core server.
With the caching, we can get it down to as much as a few milliseconds.
> To render the cache as invalid, we inspect the last modified time of the directory to
confirm whether a reload is needed.
