Phoronix: GNOME's VTE Seeing Improvements For Faster Terminal Performance

GNOME developer Christian Hergert recently demonstrated how Linux terminal emulators have the potential of running much faster. At the time it didn't sound like he would pursue the matter further but more recently he's begun working on folding some performance improvements into GNOME's VTE for a faster terminal experience...

What about input latency too?

Even slow terminals emulators feel snappy these days, but it's good to see continued effort on performance.

Maybe you need faster hardware? Surely Ryzen 7950X3D and RTX 4090 Ti are fast enough no matter what code you throw at it?

I haven't gotten to re-working the GSource schedulers, but VTE does have different IO priorities for input vs output. I do plan to tweak that eventually, and make the drawing/layout tied to frame clock cycles.

I didn't plan on working on the prototype further. The goal from the beginning was always to improve VTE.

In terms of latency, VTE based terminals certainly could do better, per https://lwn.net/Articles/751763/

Well there Mr. Duderino, thanks for dude-ing on up the speediness and latency and being a real dudebro.

Now we just need to find devs for Tilix and have a superzippy tiled terminal for GNOME instead of using Konsole which always feels out of place.

Anyway dude, you are The Dude. Keep on dudeifying!

I would love an update article like those or an addendum covering new terminal emulators too plus rerun benchmarks in vte ones and others.

Alacritty, Kitty, eDEX-UI, Simple Terminal, Tilda, ROXTerm, Eterm, LXTerminal, xfce4-terminal, Terminology, Deepin Terminal, LilyTerm, Sakura, Extraterm, DomTerm, Tabby, Rio Terminal, Zutty... and the one in Arcan.

Interesting. Qt seems to have lower latency then GTK3. Another KDE win. Or you could say Kwin.
