DF General Discussion / Re: Setting df to use more cpu?
« on: July 11, 2014, 12:21:05 pm »If you really only have 3 cores, I suspect there's something wrong with your computer as computers are usually designed around multiples of 2 (it's a binary thing).
Not true. AMD Triple cores work perfectly fine, AMD and Intel have hex cores, and Intel's Xeons are actually built around 5 and 10 cores right now.
3 cores - 33% max
4 cores - 25% max
6 cores - 16% max
8 cores - 12% max
12 cores - 8% max ()
OP, just remember that even if your CPU utilization is anything like Thief^'s chart, the cpu isn't necessarily suffering in performance. You're seeing a snapshot of the CPU activity. Windows Taskmanager gives you an update every 500ms I think. During that time each core has had about 1.5 billion cycles to to do things. The cpu scheduler has been bouncing the DF thread around your cores multiple times while DF waits for the memory access to clear, and letting other processes use some of the core while it waits. The actual DF thread is running at 100% on one core until it needs more data, at which point it may be hefted to another core for optimization purposes.
