So as I have written before I've been playing with maps and renderers and found this very interesting thing. My old home laptop which is a 5 year old Sony VAIO FE11S with a intel T2400 CoreDuo 1.86GHz CPU, 2GB ram and a NVIDIA GeForce Go 7400 256MB is as fast a Intel XEON E5520 with 8GB ram and ATI FirePro v5700 video card. I've run the code on both machines and the difference is minimal, so what is wrong here? Well after testing there is nothing wrong on the code, there are no dead locks or threads waiting for each other. What is wrong is the video card drivers. On my VAIO I still have Windows XP SP3 and a NVIDIA driver from 2006 (because Sony doesn't allows me to install the latest from NVIDIA). On the fast desktop I have Ubuntu 64 bit with the crappy ATI proprietary driver. This ATI driver is the key here since on Windows all my rendering is done using Java2D with the DirectDraw pipeline on and it is amazingly fast, it is also true if I use the OpenGL pipeline but the OpenGL driver is not as good as DirectX. On linux the driver is so crap that all rendering is done in software and a machine which I expected to be say 10x faster (it has 6x more cores, it is 64bit and the OS is also 64bit) it just sucks.
