Both RDBMS have good performance. Lots of the issues we ran into really are related to scale. If you know that your data set will never be particularly large, most of these issues will not come up. Other issues like managing replicas, promo

I didn't know that Terminology has GPU acceleration. I would be happy to include this in the future!

Thanks for this additional feedback. It sounds like we should create an XCode project from scratch to get many of the defaults and figure out how to bridge this with our current implementation.

"miss the point" feels a bit strong. Rather, I get the impression Alacritty's values don't match your own values in a terminal emulator, and that's totally OK. Historically, input latency hasn't been considered

Thanks for this clarification. I don't see any reason we couldn't support this given that info. We haven't intentionally opted out of this that I know of, we just didn't start Alacritty from an XCode project on macOS.

The hardest part about supporting things like this on macOS is that they often require a lot of additional code or a certain design whereas on Linux, a lot of these features are provided by the window manager. I don't consider it contr

We tried to strike a balance between "commonly accepted as fast" terminal emulators and coverage of "commonly used" terminal emulators. Termite gets us libvte-based terminals (like gnome-terminal), urxvt is generally con

Thanks for this feedback! We haven't heard a ton of complaints about the input latency, and comments like this help us to prioritize issues. This has been mentioned in two discussions today, so perhaps it's time to address this. I

The article you linked is specifically about latency. There are other factors that contribute to overall terminal experience such as high frame rate and high throughput. Once latency reaches a "good enough" level, it becomes a non

Word of caution when reviewing this report: it doesn't take into account vblank period. If you hit a key just after a monitor refresh, you're not going to see it until the next refresh cycle which is typically up to 16ms later. Th

We can do better in Alacritty. For those interested, I've filed a bug on our issue tracker about where this latency is coming from and what can be done: https://github.com/jwilm/alacritty/issues/673 At t

The blog post mentions integrating with WebRender as an alternative rasterizer on capable systems. Could performance of the GPU-based rasterizer ever get to the point that WebRender's glyph cache is no longer needed? After glancing qui

There's a known bug when using Mesa that kills performance. Hopefully we'll get it resolved soon!

Vulkan is not yet supported on macOS. There are plans for a Vulkan renderer, but cross-platform support will come first.

Generally continuously, but it depends on how you scroll. If you're in `less` for example and holding the down key, you will probably see one line at a time, and it should be very smooth. It's possible with high key repeat rates t

The tiling WM argument has basically sold me at this point. I'm expecting to open an issue about adding this feature behind a compile-time flag.
