    Phoronix: One Of The Reasons Why Linux 5.5 Can Be Running Slower

    Going back to the start of December with the Linux 5.5 merge window we have encountered several significant performance regressions. Over the weeks since we've reproduced the behavior on both Intel and AMD systems along with large and small CPUs. Following some holiday weekend bisecting fun, here is the cause at least partially for the Linux 5.5 slowdowns.

            Just curious to know if Michael extracts / checks out the kernel and compiles in tmpfs? It's much faster than on SSD/HDD.

              Sadly, most page operators don't care for their user's privacy or usability. Requesting a page from this article with and without blocking invasive megacorps:

              1317% http requests
              596% download size
              336% loading time
              ∞% privacy invasion

              Just a reminder that this is not an option. You violate EU law btw.

                not to mention the continuous higher CPU load the entire time the page is open because of animated ads, and ads frequently covering up content on mobile.

                  As of January, 2019, Dedoimedo added you to his very exclusive list of 'Greatest Sites on the Internet':

                  "Greatest sites on the Internet"

                  https://www.dedoimedo.com/greatest_sites.html

                  "Latest entries:...
                  January 2019: Phoronix ..."


                  "Phoronix
                  "Category: Hardware, Linux

                  "Phoronix is a website dedicated to Linux. More specifically, Linux hardware reviews, performance and open-source benchmarks. In a world dominated by fluff, hard numbers are hard [sic] to come by, and Phoronix is one of the few sources that follows the rigor of proper experiment. For the past fourteen years, it has provided consistent, practical information on Linux systems, their speed and how well Linux works on various hardware platforms, using its own custom-built test suite.
                  If you'd like to know whether you should use open-source or proprietary GPU drivers, whether to buy this or that processor and what kernel to run on it, how long your battery will last, or how your latest Linux game is going to behave, Phoronix is a great place to start your quest. One of the few remaining bastions of quality in the diminishing realm of Tux. Quite recommended."


                  I am ashamed to admit that I heartily concur with Dedoimedo's assessment--in spades--and have been availing myself of all your high quality and hard, selfless work with ADBLOCK PLUS and PRIVACY BADGER enabled on my machines.. I felt really badly when I discovered this, and have made certain that this will no longer happen.

                  Perhaps--no, make that "It is a certainty that..."-- a little bit of 'nagware' on your part, very periodically, would not be inappropriate.

                  Best regards...
