I'm running Photoshop CS6 on a late 2011 MBP 17" with 16GB RAM.
My question relates to process resource usage of Photoshop. Right now I am applying a Nik Silver Efex filter to a very large tradeshow image. I realize this is going to take some time no matter what. However, in Activity Monitor, the process line for Photoshop shows it at around 100-110% CPU. The bottom CPU tab (system totals) is showing % Idle at 80-85%. Is that normal?
To me those numbers suggest that Photoshop is only utilizing 15-20% of my total processor capability. If I look at the expanded processor view, four of the cores are showing low-moderate usage, and the other four are completely empty. I'm not sure what's going on.
Oh, and I contacted Nik support already and they said that their software works within Photoshop, so any performance issues stem from Photoshop itself.
That depends on how the code for that third party plugin is threaded.
If it is not threaded, then it will only use one core.
Considering Intel's white paper on Nik Silver Efex 2 and the i7 processor (which I have)... I'm assuming they fully optimized it for such.
