Multiprocessor support

[Rick Brewster]

Paint.NET slices up many compute-intensive tasks onto multiple threads. These tasks include resizing an image (Image->Resize), image composition (layers -> flat bitmap), image rendering (flat bitmap -> intermediate buffer, which includes zoom in/out processing), effect rendering, PDN format loading and saving, and rendering of scaled/rotated pixels with the Move Selected Pixels tool.

hmm... i've only begun to use multiple threads.

I've read something on the Pentium 4 HyperThreading implementation being flawed, and in some cases degrade performance, where as a proper implementation would have only performance gains and never performance hits.

@ .NUB That's the problem with Hyperthreading, you got only 1 CPU thats must do multiple threads and in most cases it's slowing down in HT mode

HyperThreading enabled will degraded performance under heavy load.

It was really made so that when your playing a game, the unused chip time can be doing some ( normal background system task aka light loads ) instead of being idle.

66% = game, 33% = idle

to

66% = game, 33% = anything running in the background

the problem is if either HyperThread1 has a very heavy load and halts nothing comes out HyperThread2 until that HyperThread1 finshes what it is doing.

HyperThreaded is NOT a true multiprosseor!

Dual-Core & Dual-CPU will greatly improve speed

HT will little bit improve speed but you will be better off
