Hi,
Framerate's not far from glxgears natively under OpenSolaris. It appears
that there might be an issue with texture transfers?..
I tested OpenGL texture download times using no buffer objects.
In the Fedora 10 zone with 195.36.15 libs with lofs hosting
/tmp/.X11-unix:
glTexImage2D(GL_RGB) 561.8 MB/sec
glTexImage2D(GL_RGBA) 624.4 MB/sec
glTexImage2D(GL_BGRA) 675.7 MB/sec
glTexImage2D(GL_ABGR_EXT) 636.9 MB/sec
glTexImage2D(GL_LUMINANCE) 1221.0 MB/sec
On bare metal b136 with 195.36.15:
glTexImage2D(GL_RGB) 1056.5 MB/sec
glTexImage2D(GL_RGBA) 1420.4 MB/sec
glTexImage2D(GL_BGRA) 3645.1 MB/sec
glTexImage2D(GL_ABGR_EXT) 1765.3 MB/sec
glTexImage2D(GL_LUMINANCE) 2942.3 MB/sec
With BGRA, which is a native format, the Fedora zone lofs transport
is about 5x slower but other formats are only 2-3x slower than
bare metal.
Do the GoogleEarth framerates you see on bare metal Fedora 10
run about 5x faster than the Fedora zone or much lower?
