Resultaterne af testen af effektiviteten af de optimeringer, der er tilf\u00f8jet til VTE-biblioteket (Virtual Terminal library), som er en del af GNOME 46-udgivelsen, er publiceret. Under testen blev responstiden i terminalemulatorerne Alacritty, Console (GTK 4), GNOME Terminal (GTK 3 og 4) og VTE Test App (et eksempel fra VTE-repositoriet) m\u00e5lt ved opstart i Fedora 39 med GNOME 45 og i Fedora 40-beta med GNOME 46. Alacritty-applikationen bruger ikke VTE-biblioteket og blev valgt som benchmark, da den, if\u00f8lge tidligere tests, er en af de hurtigste terminalemulatorer. Der blev anvendt en hardwaref\u00f8ler baseret p\u00e5 en Teensy-platine til at m\u00e5le tiden mellem tastetryk og fremvisning af information p\u00e5 sk\u00e6rmen. <\/p>\n

VTE-biblioteket tilbyder en f\u00e6rdiglavet GTK-widget, der bruges i forskellige terminalemulatorer til GNOME, herunder GNOME Terminal, Console, Black Box, Tilix, Terminator og Ptyxis. I GNOME 46-versionen er de interne strukturer i VTE blevet grundigt omarbejdet, hvilket, if\u00f8lge udviklerne, har f\u00f8rt til hurtigere operationer, hvor pr\u00e6stationsgevinsterne i testene n\u00e5ede op p\u00e5 40%. Praktisk set har optimeringerne resulteret i reducerede forsinkelser ved rendering i konfigurationer med GTK 4. Tidligere var forsinkelsen ved tastaturindgang i Console og GNOME Terminal m\u00e6rkbar, hvilket afholdt mange brugere fra at bruge de indbyggede terminalemulatorer til GNOME. Denne problematik blev l\u00f8st med VTE version 0.76. <\/p>\n

Uafholdt uafh\u00e6ngig test bekr\u00e6ftede en markant reduktion i input-forsinkelsen i applikationer baseret p\u00e5 VTE, hvilket observeres ikke kun i enkle, men ogs\u00e5 i komplekse scenarier med terminalbrug. For eksempel, n\u00e5r man bruger neovim, faldt input-forsinkelsen i terminalemulatorerne baseret p\u00e5 VTE til niveauet for den hurtigste terminal, Alacritty. Is\u00e6r i testen relateret til brugen af v\u00e6rkt\u00f8jet «cat» faldt reaktionstiden p\u00e5 tastetryk i Console og GNOME Terminal fra 40 til 12 ms, mens testens scrolling i neovim faldt fra 45 til 23 ms.

Forbedringen af ydeevnen med den nye version af VTE-biblioteket er ogs\u00e5 blevet bem\u00e6rket i tests\u00e6ttet vtebench, som m\u00e5ler l\u00e6setider fra PTY-enheden og parseringsydelse (rulle- og mark\u00f8rbev\u00e6gelser). I de fleste tests sl\u00e5r Alacritty-terminalen Console og GNOME Terminal, men forskellen med de sidste er ikke s\u00e5 udtalt som tidligere. En del af forskellen for GNOME Terminal kan forklares med omkostningerne ved at underst\u00f8tte tilg\u00e6ngelighedsfunktioner.
