Performance tuning options

Although rendering performance is often dominated by the combination of image resolution, shading parameters, and input scene, performance can be be further tuned by adjusting the number of worker threads, and the spatial subdivision parameters. Tachyon normally sets the number of worker threads to match the number of available CPU cores. In some cases, such as when running Tachyon on a large shared memory system that is already under load from other processes, it may be beneficial to limit the number of worker threads to a number smaller than or equal to the number of idle processor cores.
