There's a small subset of systems experiencing this. Do you happen to have a Radeon video card? In the profile I looked at, glClear was calling down into (through libxcb) __poll_nocancel which was eating 99% of the CPU time. I'm n

The renderer is custom in order to have complete control over when and how the screen is drawn.

As Steve mentioned, it was mostly for ffi. There's also a few places where I'm doing my own bounds checking in order to provide nicer error messages. After doing the bounds checking, doing an index operation without the standard l

Even so, I do plan to add a Vulkan renderer at some point using vulkano. My hope is that the build script can choose the best option at compile time.

From what I understand, screen should be roughly equivalent. I mention tmux because it's my multiplexer of choice.

I may be reconsidering this position[0]. If scrolling support can be added in a non-intrusive way behind a feature flag (so it could be completely compiled out), it could potentially have a place in Alacritty. [0]: https://news.y

Thank you for the suggestion! I've had a few comments suggesting similarly. I plan to investigate this as time permits.

That's the plan! Most components of Alacritty are platform agnostic aside from font loading, font rasterization and setting up a pty.

Thank you for the thoughtful comment. There's been a lot more pushback on the scrolling decision than I had anticipated. It's not something I want in my terminal, but it seems that a simple feature like this is essential for other

Comparing it with Mozilla's Servo project (specifically WebRender) would be more accurate.

The amount of time spent doing GPU work is rather small. Battery life tends to be better on my Macbook with Alacritty than with other terminals. This seems to suggest that power consumption is actually less than with CPU based renderers (an

Should probably redirect that to the blog; thanks for the notice!

Just for completeness, there is one other major unstable feature that Alacritty requires . #![feature(step_trait)]. I forget the precise details, but I believe this was required for using newtype wrappers as a `Range` for indexing. Specifi

Glyphs are rasterized once and stored in a texture atlas. When rendering a glyph, the fragment shader pulls from that texture. Once loaded, the glyph stays loaded for the duration of the program.

This is planned once Alacritty reaches an alpha release. Today's release is considered pre-alpha and is source-only.

Nope. The idea is that perf should be good enough that it's not necessary. withoutboats and I are hopefully going to collaborate and add notty protocol support to Alacritty. This should make text splits as performant as GUI splits.

Terminal performance is fine at smaller sizes and with less going on. In a multi-pane tmux window with vim, performance issues start to become noticeable. Many people I've talked to have experienced a situation where a bunch of output

We use PgBouncer as well. It's still useful to have a connection pooler within the application for ensuring connections are still good, reconnecting as needed, and making it easy to check out a connection.

It's essentially what serde is doing internally. As an author, you don't have to do any of the work, though. I struggle to imagine how a dynamic language could provide equivalent functionality without the call side becoming more c

We actually did consider them briefly. The problem in this case was having zero in-house knowledge about the technologies nor anybody particularly experienced with FP. We did not want to take on that much risk.
