I'm running CA Premier x6, 64bit, v. 16.4.0.81 (7/21/14). I have 3+ year old Dell Studio XPS 9100, Intel I7-930 (2.8Ghz, 8MB cache), 12GB RAM (1333 DDR3). This is a quad core processor. Video is AMD 5670 (1GB), 64bit. Win7, 64 bit. When I initiate a Ray Trace, CPUs are buried @ 100%. But interestingly, only about 25-35% (3-4GB) of system memory is used. When I open Performance Monitor, I see that Ray Trace spawns only 9 threads, while CA itself has opened 20+ threads under the same Process ID (PID). I know that the video card is fairly pedestrian, and that I can throw in a Radeon 6970, 2GB, 256-bit card for about $100. Likewise, I could go to a Samsung 840 SSD for about $200, and really improve the overall performance of the computer. But would that really help Ray Trace? I've been reading about how resource intensive Ray Trace is, but what I'm seeing in PerfMon has me reconsidering my upgrade plans. Is Ray Trace really so CPU-bound? Are there any config/parameter files that can be tweaked in order to allocate more threads to CA/Ray Trace? PerfMon tells me my computer's resources like IO and memory are underutilized, except for CPU. Are there any tuning parameters possible? Or should I be thinking exclusively about processor speed and cores?
Thanks for any thoughts.
