From 9d82af29df47e731749f9a346a630356975153d2 Mon Sep 17 00:00:00 2001 From: Monroe Linden Date: Wed, 17 Nov 2010 16:01:46 -0800 Subject: SOCIAL-233 WIP Better performance (improve loading time of webkit instance) The plugin system will now keep a spare running webkit plugin process around and use it when it needs a webkit instance. This should hide some large portion of the setup time when creating a new webkit plugin (i.e. opening the search window, etc.) --- indra/llplugin/llpluginclassmedia.cpp | 2 +- indra/llplugin/llpluginclassmedia.h | 2 ++ indra/newview/llviewermedia.cpp | 50 ++++++++++++++++++++++++++++++++++- indra/newview/llviewermedia.h | 4 +++ 4 files changed, 56 insertions(+), 2 deletions(-) diff --git a/indra/llplugin/llpluginclassmedia.cpp b/indra/llplugin/llpluginclassmedia.cpp index cd0689caa6..4001cb183f 100644 --- a/indra/llplugin/llpluginclassmedia.cpp +++ b/indra/llplugin/llpluginclassmedia.cpp @@ -160,7 +160,7 @@ void LLPluginClassMedia::idle(void) mPlugin->idle();
