Why is Firefox so slow on Linux then?
I'll try it again at some point, but disable TreeStyleTabs, that might have been one of the causes for the slowness.

> it's still slow and painful in comparison to compiled languages Something tells me your opinion about Java is stronger than your experience. Java IS a compiled language. It just happens at runtime. https://www.oracle.com/technical-resources/articles/java/arc... I see this as yet another example of people here repeating a severely outdated statements about the JVM ecosystem.
Sure. Of course Oracle wants you to believe that Java is faster than C.
I'm under the impression that you are not interested in educating yourself on the topic, however if I'm mistaken, have a look at some reasons why Java can be as fast or faster than c/cpp:
- TLAB (thread-local allocation buffer)
- Escape analysis
- Mono- and bi-morphic callsite optimizations
- JIT in general (dead code elimination, implicit null checks, CHA-based optimizations, etc).
Also, you don't have to use Oracle JVMs. There's IBM's J9, OpenJDK-based Zulu, or commercial JVM from Azul (Zing).
Off topic maybe, but my Razer Blade 15" has been and absolutely wonderful replacement for my MBP. The build quality feels just as nice, and none of the weird touchbar issues. (Running Ubuntu 19.10 presently, only issue: had to disable the USB-C port to allow it to sleep). The arrow keys are also in a slightly wonky location. It's been very disruptive to have Apple quality tank, and I'm glad they finally went back to…
For Firefox rendering being slow, I forced the Ubuntu Firefox to use Wayland the other day (my login session was already wayland but Ubuntu doesn't default to making firefox using it), and the difference is night and day. Everything is so much faster and super smooth.
Given all the ads for Firefox on HN I keep trying it but it's insanely slow. I don't think it's intended to be like this, not sure where to begin troubleshooting.

ThinkPads be like "Are we a joke to you?"
I used i3 for a long time. After a while it didn't feel that fast. Yes switching was very quick but often it got in the way. So many applications have little windows that pop up. They didn't play nice with i3. I also had the issue of a limited keyboard and shortcut keys. I use a Kinesis advantage. I don't have a windows key. So I used alt as a super key. This meant that I often couldn't use application shortcuts. It…
For me it was remembering what my bindings were for every little thing. I’m a guy who built his own keyboard for extra macro keys. I have 12 extra off the left side. It worked out very nicely, and it was a pretty smooth experience. Until I was using my computer to laze about at 11pm with a slightly foggy mind. I just don’t want to think about how to move incredibly quickly around the computer. Easy point and click is…
Right. This is an important thing to note.
It takes a lot of mental energy to remember all of these things if they are not already imbued into your brain as effortless muscle memory. Sometimes that energy is better off spent solving the problem you're trying to solve. This is why after about a year of using Vim, I still use the mouse once in a while.
I remember once reporting a bug with the Microsoft Terminal (I use WSL 2 on Windows) on Reddit and when I mentioned mouse support didn't work inside of programs like Vim, it was the most down voted comment I ever created on any platform with swarms of folks saying I wasn't using the terminal as it was supposed to and that I must be an idiot for wanting to select text in Vim with a mouse.
Luckily they fixed the bug (it ended up being one of the highest priority bug fixes they had).
If that's the main reason, how about yabai on Mac? https://github.com/koekeishiya/yabai
> The primary function of yabai is tiling window management; automatically modifying your window layout using a binary space partitioning algorithm to allow you to focus on the content of your windows without distractions. Additional features of yabai include focus-follows-mouse, disabling animations for switching spaces, creating spaces past the limit of 16 spaces, and much more.

On the one hand, yes, Apple is generally extremely hostile towards users tinkering with their platforms, be it iOS or macOS, so it theoretically should be harder. On the other hand, on the pre-2016 models, the components in use are largely off-the-shelf components, much like other manufacturers. The major difference between Apple laptops and other vendors laptops is that the variation of components in use is signific…
Pre-2016 will start dying though. For new hardware, we're pretty much left with macbook which is definitely broken, or literally anything else, which may be broken, but often isn't. If you're going for brands, most Dell, Thinkpad, HP, etc. (not lowest price) laptops will work just fine with linux. Some even come as certified compatible.
I guess, but my 2007 and 2010 laptops still work OK.

Java has been broadly used in HPC and low-latency trading software for years now. That's not only because much more attractive time-to-market but also because in many cases Java is on par with c/cpp when it comes to performance. Sometimes even better.

And no, the actual HFT stuff is written in C++.
