CPU Affinity of Explorer.exe in Windows 7?

[serjio]

First, thanks to Dev for recent updates, including the updates which recognized more than 32 cores. Great updates!

I've recently found that I see better overall performance on my dual E5-2697 v2 (24 Logical / 48 HT Cores) by attaching explorer.exe to cores 0-3 and 24-27 (the first 2 logical cores on each CPU).

When working in 3D applications; programs like After Effects. I've found by assigning those programs to all cores MINUS the the first 2 on each processor; and assigning/allowing basically only windows processes to the first 2 cores.

So when the system ramps up basically maxing out both CPUs, explorer.exe and other processes have 4 logical cores of freedom, and the system stays very stable, no delays navigating windows, etc. I even linked firefox to these cores.

My only question is when you do this, a warning pops up... is there really any danger in doing this? I realize for people running systems with only 4 or 8 HT cores it would make little difference, but with 48; is there any harm in assigning processes to specific cores to keep the system highly responsive?

Thanks again!

I'm glad you have put Process Lasso to good use!

The warning is shown out of an abundance of caution. There are no known problems with the scenario you describe.
