Caching via OS support won’t work:
Single server = Potential bottleneck !
Minimize voxel-fetching latencies
(100Mbit/s 1MB = 80ms = 160 million cycles !!!)
Even better for more CPUs
Latency-hiding works !
Server bottleneck after 12 CPUs
Distribute model server!
Framerate (640x480) : 3.9 - 4.7 fps (seven dual P-III 800-866 Mhz CPUs, NO SSE)
Framerate: 1.4-2.2 fps (NO SSE)
… other complex models are welcome…
