# @summary
# Installs and manages the MPM `worker`.
#
# @param startservers
# The number of child server processes created on startup
#
# @param minsparethreads
# Minimum number of idle threads to handle request spikes.
#
# @param maxsparethreads
# Maximum number of idle threads.
#
# @param threadsperchild
# The number of threads created by each child process.
#
# @param maxrequestsperchild
# Limit on the number of connectiojns an individual child server
# process will handle. This is the old name and is still supported. The new
# name is MaxConnectionsPerChild as of 2.3.9+.
#
# @param serverlimit
# With worker, use this directive only if your MaxRequestWorkers
# and ThreadsPerChild settings require more than 16 server processes
# (default). Do not set the value of this directive any higher than the
# number of server processes required by what you may want for
# MaxRequestWorkers and ThreadsPerChild.
#
# @param threadlimit
# This directive sets the maximum configured value for
# ThreadsPerChild for the lifetime of the Apache httpd process.
#
# @param listenbacklog
# Maximum length of the queue of pending connections.
#
# @param maxrequestworkers
# Maximum number of connections that will be processed simultaneously
#
# @see https://httpd.apache.org/docs/current/mod/worker.html for additional documentation.
