From 684cdd0298dafe51f4091d27b2bcc6acee96fc9f Mon Sep 17 00:00:00 2001 From: Lorin Hochstein Date: Sat, 1 Nov 2014 19:31:04 -0400 Subject: [PATCH] Docs: accelerate mode -> accelerated mode The docs sometimes referred to "accelerated mode" as "accelerate mode". This patch changes it to "accelerated mode" everywhere. --- docsite/rst/intro_configuration.rst | 6 +++--- docsite/rst/playbooks_acceleration.rst | 14 +++++++------- 2 files changed, 10 insertions(+), 10 deletions(-) diff --git a/docsite/rst/intro_configuration.rst b/docsite/rst/intro_configuration.rst index cf4b9b6122..a9f50f804f 100644 --- a/docsite/rst/intro_configuration.rst +++ b/docsite/rst/intro_configuration.rst @@ -662,8 +662,8 @@ recommended if you can enable it, eliminating the need for :doc:`playbooks_accel .. _accelerate_settings: -Accelerate Mode Settings ------------------------- +Accelerated Mode Settings +------------------------- Under the [accelerate] header, the following settings are tunable for :doc:`playbooks_acceleration`.

There is no additional public key infrastructure to manage, and this does not require things like NTP or even DNS. Accelerated mode can be anywhere from 2-6x faster than SSH with ControlPersist enabled, and 10x faster than paramiko.
