comment How do I permanently set the affinity of a process?
@NateKerkhofs: Yes it should. I made my own start-with-affinity wrapper once that did nothing besides set its own affinity and then spawn the target application.

comment Is there any way to fix Google Chrome's issue with fonts?
In the Jpeg both browsers look acceptable but not amazing, neither is clearly better. But that could be the compression artifacts.

Can you upload a lossless format instead like PNG? I can't tell whether you have subpixel antialiasing because the jpeg artifacts mess it up.

Is it a high DPI display? Is Display Scaling enabled or disabled for Chrome (in the OS-level compatibility options)? Are you using Chrome's own experimental high DPI support?

comment Do recommended battery charging practices for a laptop apply to an ultrabook (with non-removable battery)?
There's some good advice here, but the physical chemistry portions are... badly confused.

comment How can manufacturers put the specs of overclocking speeds when the whole point of overclocking is it's not known?
@Stefan: One thing that isn't immediately clear, of course, is that a program can be CPU bound but much less than 100% CPU load. That happens if some of the cores or some of the arithmetic units in a core are going unused. And that Turbo Boost accounts for iGPU load as well, because the CPU and on-die GPU share the power and thermal envelope.

@Stefan: You said I'm incorrect, and then agreed with everything I wrote.

Turbo Boost is an overclock, because it is above the frequency at which the CPU can safely run indefinitely at 100% load.

USB soundcards should be an option as well...

comment How can Windows dump the complete RAM in the hibernation file so fast?
@LightnessRacesinOrbit: I said "only accesses the disk when I ask it for something". Entries are made to access_log and error_log only when I send a (e.g. HTTP) request. Besides which, these small writes don't cause contention for the reasons already given.

comment How can Windows dump the complete RAM in the hibernation file so fast?
@LightnessRacesinOrbit: Small writes don't hit the disk, they go into cache and get written out whenever they don't cause contention... and the OS can allocate a block to reduce seeking (due to abstractions like logical block addressing, this usually means sequential allocation, causing fragmentation, but removing contention between multiple writers). Non-Windows systems have it even better -- with e.g. syslog, you don't have logging from multiple background processes.

comment How can Windows dump the complete RAM in the hibernation file so fast?
@LightnessRacesinOrbit: That seems... unusual even during normal operation (everything except entering and leaving hibernation). I know that when I catch a background task hitting the disk, I uninstall the sucker and replace it with something that only accesses the disk when I ask it for something.

comment How can Windows dump the complete RAM in the hibernation file so fast?
@LightnessRacesinOrbit: CPU contention will make hardly any difference at all. Lack of I/O contention is a big deal, but this answer has already stated that seeking kills performance, and seeking, not lack of overall bandwidth, is the main issue with I/O contention.

@MSalters: But relocation creates a private copy of the page, and it's then extremely difficult to determine whether any other modifications have been made to the private copy. Contrast with mappings that didn't require fixup, and use copy-on-write. If other modifications are made, there will be a private copy. If not, the page will still be configured for CoW.
