    Neither KDE nor GNOME is the best one. Both wasting too much resources.

    Gnome is the big resource user; KDE is comparable to XFCE, less
    according to some, more depending on the 'implementation' of the KDE.

    Neon's default KDE is less than most distro's default XFCE.

    If you want low resource usage graphical, it needs to be window manager
    rather than DE.

    I understand that concept; but a DE shouldn't 'waste' ram doing the same

    uses, say, twice as much ram being whatever it is.

    I think Gnome and KDE have different goals in mind; I prefer KDE's
    goals, irrespective of the ram 'bonus'.

    That 'goal' business accounts for the relative success of such as XFCE, Cinnamon, and Mate, where the latter two are 'breakaways'/forks from
    gnome's direction.

    I uaws to have a Dell Inspiron 4000 laptop and used Mandriva
    with KDE on it but I reduced the number of Virtual Desktops and got
    adequate performance on it. That was with a 700 MHz Pentium coppertop
    and 684 megabytes of ram, 8 megabytes on the GPU. I learned a lot of
    stuff on that machine before I passed on to a former friend who had
    through neglect reduced it to a mess that was recyclable. Oh and
    it was dual-boot with XP on the other side.
    Presently occupy myself on a Dell Latitude with 16 GB
    and an i7 dual core. I used Gnome 2.4, XFCE and some other
    stuff in my 19 years using Linux. Currently running PCLinuxOS
    with KDE.

    I disagree. I found Unity really useful for laptops with smaller

    the most intuitive and best uses of limited screen real estate. Not a
    favor of the global menu and welcomed its optional implementation. The

    That is not my situation. It is a thing that can be confusing in
    Thunderbird, but no much with SeaMonkey. With newsgroups the "Reply"
    button defaults to "Reply to Newsgroup" with a dropdown option to "Reply
    to sender". And there is a second button "Reply All" button defaults to
    "Reply to Newsgroup and Sender" with dropdown option for "Reply to all recipients", whereas Thunderbird "Reply" button is "Reply to sender" and
    the "Followup" button for replying to the newsgroup which can confuse
    people.

    Also I noticed the the undisplayed posts show up in Local Folder Sent
    and do have the correct attributions. I have been getting newsgroup
    reset notices lately and also notice if a toggle between the secure and non-secure ports I can send posts for awhile. I think it is an ES issue.

    One approach is the two wikipedia articles on DEs & WMs. One oversimplification is to say that the WM is one part of a larger
    collection of parts making up the DE. Some WMs use some DE elements to
    be more DE like.

    https://en.wikipedia.org/wiki/Desktop_environment https://en.wikipedia.org/wiki/Window_manager

    The more you dig into it, the more complicated it gets, eg x-window vs
    Wayland.

    Yes, I really had hopes that Shuttlesworth's Ubuntu Phone would have

    And two days later I play with a machine (a Starfive Visionfive V1)
    where XFCE (supposedly a light-weight environment) is noticably slow,
    probably due to basic window operations being slow. This machine has
    a CPU with a 15 times faster clock than my first Linux box (a 486/66),
    runs our LaTeX benchmark 17 times as fast, has twice the number of
    cores (2 vs. 1), has 512 times more memory (8GB vs. 16MB); makes me
    wonder whether the 486 had a similarly sluggish response and I
    accepted it because I was not spoiled by better experience, or whether
    the experience was better and on this machine I see the effects of
    software bloat that is hidden elsewhere by faster and more specialized hardware. The experience when using the machine through ssh is fine,
    BTW.

    But do the heavy-weight DEs improve my workflow? No.

    If the Ubuntu default had inhibited my workflow, I would have invested
    the time to set up my twm environment.

    ...there's nothing wrong with a visually appealling UI.

    Sure. But I don't find the heavy-weight DEs visually appealing.

    And two days later I play with a machine (a Starfive Visionfive V1)
    where XFCE (supposedly a light-weight environment) is noticably slow, probably due to basic window operations being slow. This machine has
    a CPU with a 15 times faster clock than my first Linux box (a 486/66),
    runs our LaTeX benchmark 17 times as fast, has twice the number of
    cores (2 vs. 1), has 512 times more memory (8GB vs. 16MB); makes me
    wonder whether the 486 had a similarly sluggish response and I
    accepted it because I was not spoiled by better experience, or whether
    the experience was better and on this machine I see the effects of
    software bloat that is hidden elsewhere by faster and more specialized hardware. The experience when using the machine through ssh is fine,
    BTW.

    But do the heavy-weight DEs improve my workflow? No.

    ...by the same token however, unless you're rendering videos, or running a BitCoin
    "Mine"...or some other long-term CPU-super-intensive process, a "heavy-weight" DE isn't
    going to *inhibit* your 'workflow' either.

    If the Ubuntu default had inhibited my workflow, I would have invested
    the time to set up my twm environment.

    ...there's nothing wrong with a visually appealling UI.

    Sure. But I don't find the heavy-weight DEs visually appealing.

    I am sure they do. If the window manager uses OpenGL (rather than
    classical X operations), that could explain the sluggish performance.
    In that case it would really be software bloat (at least as far as
    such simple hardware is concerned).

    What's interesting, is not even the mainstream CPU designs,
    use all the features provided by current DRAM. It's been like
    that for at least four generations.

    There are no long bursts, even though long bursts are supported.
    Usually the designers are cache-line-size oriented. And this
    means an access cycle is pretty expensive (taking 100 cycles
    for a 4 cycle burst). Perhaps this design would have an
    8 cycle burst, depending on the size of the cache line.

    The forum thread suggests there is no prefetcher, or the
    stride of any prefetching function is unknown.

    And modern processors also fabricate the details of their
    transfer bandwidth. The marketing materials tends to take
    the number of channels and multiply by the theoretical bandwidth,
    when nothing could be further from the truth. The numbers
    can be off by a factor of 8, just for starters.

    In the chip business, if you don't have the local skills to design
    a particular block in a project, you can buy an IP block instead.
    It might cost $20000 depending on function. For example, the USB3
    ports on current AMD processors, were not designed by AMD. They
    were designed by Asmedia and the drivers, the copyright string
    might mention MCCI (if Asmedia is offering drivers for Windows 7
    for example). Even PHY blocks (the pads producing the super
    high speed output signals, like USB4 PHY), can be purchased.

    You don't have to design the whole chip yourself.

    At work, one of the engineers, as a demo project, bought *all*
    the IP blocks for a design (did no detailed design himself),
    and he joined them with Wishbone bus, and the chip design
    finished in 30 days. But it was merely a demo, made a hand full
    of test chips and that was it. This was likely an answer to a
    question from management "why do these projects take a year
    or two years to complete". Normally our chips were gate level,
    done 100% by the designers in-house (Synopsis). At the time, the
    IP libraries were not very comprehensive.

    I also have a friend in town, who makes IP blocks for a living.
    He designs stuff, but he never knows whether anyone uses it.
    A pretty strange form of employment.

    But then, it depends on what money you have available for buying
    IP blocks, as to whether you can do that or not. Some of our projects
    were stretched over multiple years, just for budget reasons. There
    isn't always money available for lavish spending.

    But at least for a DRAM controller, there's a chance you could
    buy a decent one.

    Maybe instead of using Ubuntu designed to use Gnome you might switch to a distro designed from the getgo to use KDE. XFCW will be
    faster on some hardware but in my opinion it gives up too much.
    Are you using Xubuntu, Linux Lite, or Lubuntu?
    Some folks think the Linux Lite is the best of these.
    But I use PCLinuxOS 64 and it keeps its KDE up to date. It is
    a rolling release which means constantly updated which is not
    an esoteric command line paackage manager but Synaptic which
    makes it incredibly simple to do upates.

    bliss - brought to you by the power and ease of PCLinuxOS
    and a minor case of hypergraphia

    The 64-byte cache line seems to be pretty optimal for general-purpose
    CPUs, so much that JEDEC has designed the recent DDR generations
    around it: DDR3 and DDR4 with 8 beats of 64 bits and DDR5 with 16
    beats of 32 bits. Optimal in the sense that cache hit rates are lower
    with longer cache lines; apparently there is not enough spatial
    locality for longer cache lines in general-purpose code.

    And modern processors also fabricate the details of their
    transfer bandwidth. The marketing materials tends to take
    the number of channels and multiply by the theoretical bandwidth,
    when nothing could be further from the truth. The numbers
    can be off by a factor of 8, just for starters.

    Intel and (since Zen) AMD seem to be pretty good at getting pretty
    close to the theoretical maximum bandwidth from a channel for
    sequential accesses. For multiple channels you of course will see
    maximum bandwidth only if the channels are accessed in a balanced way.

    But at least for a DRAM controller, there's a chance you could
    buy a decent one.

    Yes, but it seems they did not buy IP blocks (at least not good ones)
    for DRAM controller, graphics, SD controller, and Ethernet (basically everything I measured beyond the CPU core) for the JH7100 (the SoC of
    the VisionFive V1); or maybe some of these are bought, but there's a
    bottleneck elsewhere. And maybe the idea of Sifive is to be able to
    offer these things themselves (not sure how Starfive fits in).

    It certainly would fit with the original motivation of RISC-V to have
    an open architecture that can be used for student projects; so you let
    a student have a go at a memory controller; and another one at
    improving it; while with an IP block, there is AFAIK usually no way
    for you to improve it except as provided by the IP block owner.
