# == Class: openstack_project::review

# Current thinking on Gerrit tuning parameters:

# database.poolLimit:
# This limit must be several units higher than the total number of
# httpd and sshd threads as some request processing code paths may need
# multiple connections.
# database.poolLimit = 1 + max(sshd.threads,sshd.batchThreads)
#   + sshd.streamThreads + sshd.commandStartThreads
#   + httpd.acceptorThreads + httpd.maxThreads
# http://groups.google.com/group/repo-discuss/msg/4c2809310cd27255
# or "2x sshd.threads"
# http://groups.google.com/group/repo-discuss/msg/269024c966e05d6a

# container.heaplimit:
# core.packedgit*
# http://groups.google.com/group/repo-discuss/msg/269024c966e05d6a

# sshd.threads:
# http:
#  //groups.google.com/group/repo-discuss/browse_thread/thread/b91491c185295a71

# httpd.maxWait:
# 12:07 <@spearce> httpd.maxwait defaults to 5 minutes and is how long gerrit
#                  waits for an idle sshd.thread before aboring the http request
# 12:08 <@spearce> ironically
# 12:08 <@spearce> ProjectQosFilter passes this value as minutes
# 12:08 <@spearce> to a method that accepts milliseconds
# 12:09 <@spearce> so. you get 5 milliseconds before aborting
# thus, set it to 5000minutes until the bug is fixed.
