We're using a LightWave example titled "Radiosity Test Scene" for our rendering trace. According to its author, "...this scene is designed to throw off the GI engine by introducing very small detail in a large space that's almost entirely indirectly illuminated, while still rendering very fast."
This scene isn't a particularly exhaustive rendering test; it only took 13 minutes and 30 seconds to render on our Core i5-2500K-based system. However, more complex scenes yield similar results. We see that a majority of operations occur at a queue depth of one during the render process. Yet, due to the numerous small textures involved, most of the data is transferred randomly, and a significant number are moved in 4 KB blocks.
I/O Trends:
- 78% of all operations occur at a queue depth of one
- 65% of all data transferred is random
- 47% of all operations are 4 KB in transfer size
- 11% of all operations are smaller than 512 bytes in transfer size
