What is enumerated from SAM/AD by getent is controlled by /etc/nsswitch.conf
entry db_enum which defaults to:

# db_enum:  cache builtin

I changed my SAM, non-AD, non-domain system to:

db_enum:    cache local builtin

Please read the rest of the info about db_enum in /etc/nsswitch.conf and set up
your system accordingly.

If you are in a domain with AD, it will be worth your while to configure and run
cygserver service, under cygrunsrv, to cache your AD entries.
Even if you are on a SAM, non-AD, non-domain system, if you run a lot of Cygwin
processes, or use cron a lot, it will be worth your while to configure and run
cygserver service, under cygrunsrv, to cache your SAM and process entries.

If you run a lot of processes, it may be worth maximizing some entries in
/etc/cygserver.conf:

# kern.srv.cleanup_threads: No. of cygserver threads used for cleanup tasks.
# Default: 2, Min: 1, Max: 16, command line option -c, --cleanup-threads
#kern.srv.cleanup_threads 2
kern.srv.cleanup_threads 16

# kern.srv.request_threads: No. of cygserver threads used to serve
#                           application requests.
# Default: 10, Min: 1, Max: 310, command line option -r, --request-threads
#kern.srv.request_threads 10
kern.srv.request_threads 310

# kern.srv.process_cache_size: No. of concurrent processes which can be handled
#                              by Cygserver concurrently.
# Default: 62, Min: 1, Max: 310, command line option -p, --process-cache
#kern.srv.process_cache_size 62
kern.srv.process_cache_size 310
