From d17633f6c000b219b423d1268b9fed2ee2d6ccde Mon Sep 17 00:00:00 2001 From: UbitUmarov Date: Mon, 9 Nov 2015 15:06:41 +0000 Subject: replace StatisticsFPSfactor that needed to be changed with FrameTime to a simpler true or false Normalized55FPS that is now TRUE by default. Incorrectly this commit also contains changes that should had their own commits: changes to heartbeat time control ant to gathering and calculation of related statistics. --- OpenSim/Region/Framework/Scenes/Scene.cs | 59 +++-- .../Region/Framework/Scenes/SimStatsReporter.cs | 286 +++++++++++---------- 2 files changed, 179 insertions(+), 166 deletions(-) (limited to 'OpenSim/Region/Framework/Scenes') diff --git a/OpenSim/Region/Framework/Scenes/Scene.cs b/OpenSim/Region/Framework/Scenes/Scene.cs index 1952402..4e629da 100755 --- a/OpenSim/Region/Framework/Scenes/Scene.cs +++ b/OpenSim/Region/Framework/Scenes/Scene.cs @@ -361,9 +361,9 @@ namespace OpenSim.Region.Framework.Scenes /// public float FrameTime { get;
