Compared to Netflix not supporting 1080p and 4K on Linux, supporting AVIF is insignificant.

Are you sure you have frequency scaling enabled in BIOS and in kernel config?

$ zgrep -i freq /proc/config.gz
CONFIG_ACPI_CPU_FREQ_PSS=y

The Firefox 72 results presented in this article are not in line with what I am measuring on my machine. In the case of MotionMark1.1, my result is 225.64...

According to my measurements, ondemand saves about 10 Watts on desktop Ryzen at the outlet when performing light tasks such as playing a Youtube video....

You probably mean sampling_down_factor, not sampling_rate. The sampling_rate on my machine is 20000 (by default)....

Determining the performance difference [for a Phoronix article] would require reverting the patch to obtain a kernel binary running on Ice lake i7-1065G7...

I have a shared library with debug info of size 150 MB which loads in 2.1-2.5 seconds, so about 60 MB/s. You suggested the range "takes a minute...

Why would you be loading symbols if you aren't making use of the information related to those symbols?

The question is why gdb isn't starting...

That would mean that the executable, including the size of the shared libraries it uses, is at least 5 GB in size. Not many projects are that big....

The multi-threaded symbol loading is less efficient than I expected:

• Disabled: 2.50 seconds elapsed, 99% CPU
• Enabled: 2.16 seconds elapsed, 128%

Some notes:

• The multiplication almost never overflows in this case because the loop terminates due to (i*i <= test), where "test" is an

Yes, you are right. But by using floating-point division the performance of this code on Ryzen improves by a factor of 4 (from IPC=0.5 to IPC=1.94)....

In my opinion, C/C++ compilation workloads on many-core CPUs are limited by memory bandwidth and by the scheduler....

It is probable that at least one of the measurements is invalid....

I agree, via Javascript/WebAssembly a website developer can internally use any kind of image compression method. A downside is that it won't be possible...

There is no support for automatically extending web browser's list of image decoders (when an unknown image format is encountered) by pointing it to an...

I have a negative experience with undervolting, if the GPU is overclocked at the same time, causing weird triangles and invalid colors to be rendered...

I have a small script that is started from an udev rule when a monitor is plugged-in or unplugged. The script will set GPU's memory clocks to a single...

I believe it isn't that easy. Coincidentally, today I down-clocked RX 570 to 300/300 MHz shader/memory clocks while playing an 1080p/60Hz Youtube video...

Just a note: I updated GitHub issue #6561.

There are 49 closed issues and 32 new issues in the last month. Based on these two numbers it...
