From e85e3ec2a73ac35aaf911f0b1e34b234be1622da Mon Sep 17 00:00:00 2001 From: Sven Gothel Date: Fri, 6 Jul 2012 01:20:48 +0200 Subject: Enhance Bootsrapping of JOGL around 37% - 40% (1st start in new JVM) - GLProfile and GLContext* GLProfile: Enhance bootsrapping performance of loading GL*Impl class - Offthread classloading of all GL*Impl via reflection at startup reduces startup time here around 12% (800ms down to 700ms). GLContext*: Enhance bootsrapping performance of querying available GL profiles - Add PROFILE_ALIASING mode, defaults to true - can be disabled w/ property 'jogl.debug.GLContext.NoProfileAliasing' - PROFILE_ALIASING: If true (default), bootstrapping the available GL profiles will use the highest compatible GL context for each profile, hence skipping querying lower profiles if a compatible higher one is found. Linux x86_64 - Nvidia: 28%, 700ms down to 500ms Linux x86_64 - AMD : 40%, 1500ms down to 900ms - GL*Impl: - make fields final: glProfile, _context, buffer*Tracker and glStateTracker - allow null _context/glProfile in initialization (bootstrapping) - JoglVersion.getDefaultOpenGLInfo(..) - add arg: 'boolean withCapabilitiesInfo', allowing to suppres the list of caps --- make/config/jogl/gl-impl-CustomJavaCode-common.java | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'make/config/jogl/gl-impl-CustomJavaCode-common.java') diff --git a/make/config/jogl/gl-impl-CustomJavaCode-common.java b/make/config/jogl/gl-impl-CustomJavaCode-common.java index 2c3227ee5..d552bc6e4 100644 --- a/make/config/jogl/gl-impl-CustomJavaCode-common.java +++ b/make/config/jogl/gl-impl-CustomJavaCode-common.java @@ -1,7 +1,7 @@ public GLProfile getGLProfile() { return this.glProfile; } - private GLProfile glProfile; + private final GLProfile glProfile; public int glGetBoundBuffer(int target) { return bufferStateTracker.getBoundBufferObject(target, this); @@ -46,7 +46,7 @@ return _context; } - private GLContextImpl _context; + private final GLContextImpl _context; /** * @see javax.media.opengl.GLContext#setSwapInterval(int) -- cgit v1.2.3
