From 613e33ee8ffc1f2b9c5db1e1b5bb5253a159ed6d Mon Sep 17 00:00:00 2001 From: Sven Gothel Date: Mon, 4 Nov 2013 15:07:14 +0100 Subject: Bug 888 - Validate CPU Runtime Performance: X11GLXGraphicsConfiguration.GLXFBConfig2GLCapabilities(..) X11GLXGraphicsConfiguration.GLXFBConfig2GLCapabilities(..) ran over all FB configs and for each it grabbed native config values separately. Fetching them in bulk mode saves around 7% of this function's cost. Also reuse XRenderPictFormat instance for 'XRenderDirectFormat XRenderFindVisualFormat(..)' call, saving a few NIO creation cycles w/ StructAccessor. Biggest savior is X11GLXGraphicsConfigurationFactory.chooseGraphicsConfigurationFBConfig()'s fast path w/o chooser and usable 1st FBConfig. Here we only issue 'GLXFBConfig2GLCapabilities(..)' on the first valid entry. Test w/ 50 X11GLXGraphicsConfigurationFactory.chooseGraphicsConfigurationFBConfig() invocations: - pre change: 1.708 ms - post change: 650 ms Time is no spent almost solely on native glXChooseFBConfig (546ms). --- .../x11/glx/X11GLXGraphicsConfiguration.java | 144 +++++++++++++++------ .../glx/X11GLXGraphicsConfigurationFactory.java | 46 ++++--- 2 files changed, 129 insertions(+), 61 deletions(-) (limited to 'src/jogl/classes/jogamp/opengl/x11') diff --git a/src/jogl/classes/jogamp/opengl/x11/glx/X11GLXGraphicsConfiguration.java b/src/jogl/classes/jogamp/opengl/x11/glx/X11GLXGraphicsConfiguration.java index 4d1ed3985..ee3e1a3d7 100644 --- a/src/jogl/classes/jogamp/opengl/x11/glx/X11GLXGraphicsConfiguration.java +++ b/src/jogl/classes/jogamp/opengl/x11/glx/X11GLXGraphicsConfiguration.java @@ -34,6 +34,8 @@ package jogamp.opengl.x11.glx;
