Resultaten fr\u00e5n utv\u00e4rderingen av effektiviteten av de optimeringar som lades till i VTE-biblioteket (Virtual Terminal Library) och ing\u00e5r i version GNOME 46 har publicerats. Vid testningen m\u00e4ttes responsen hos gr\u00e4nssnittet i terminalemulatorer som Alacritty, Console (GTK 4), GNOME Terminal (GTK 3 och 4) samt VTE Test App (ett exempel fr\u00e5n VTE-f\u00f6rvaret), n\u00e4r de k\u00f6rdes i Fedora 39 med GNOME 45 och i Fedora 40-beta med GNOME 46. Alacritty anv\u00e4nder inte VTE-biblioteket och valdes som referens, eftersom det, enligt tidigare tester, \u00e4r en av de snabbaste terminalemulatorerna. F\u00f6r att m\u00e4ta anv\u00e4ndes en h\u00e5rdvarusensorn baserad p\u00e5 Teensy-kortet som m\u00e4tte tiden mellan knapptryckning och informationens framtr\u00e4dande p\u00e5 sk\u00e4rmen. <\/p>\n

VTE-biblioteket tillhandah\u00e5ller en f\u00e4rdig GTK-widget som anv\u00e4nds i olika terminalemulatorer f\u00f6r GNOME, inklusive GNOME Terminal, Console, Black Box, Tilix, Terminator och Ptyxis. I version GNOME 46 har VTE genomg\u00e5tt betydande omarbetningar av interna strukturer, vilket enligt utvecklarna har lett till snabbare operationer, d\u00e4r prestationsvinsterna i testerna uppgick till upp till 40%. Fr\u00e5n ett praktiskt perspektiv har optimeringarna resulterat i minskade f\u00f6rdr\u00f6jningar vid rendering i konfigurationerna med GTK 4. Tidigare var f\u00f6rdr\u00f6jningarna vid tangentinmatning i Console och GNOME Terminal m\u00e4rkbara, vilket avskr\u00e4ckte m\u00e5nga anv\u00e4ndare fr\u00e5n att anv\u00e4nda de inbyggda terminalemulatorerna f\u00f6r GNOME. Detta problem har \u00e5tg\u00e4rdats med version VTE 0.76. <\/p>\n

Oberoende tester har bekr\u00e4ftat en m\u00e4rkbar minskning av inmatningsf\u00f6rdr\u00f6jningar i VTE-baserade applikationer, vilket observeras inte bara i enkla, utan \u00e4ven i komplexa anv\u00e4ndningssituationer f\u00f6r terminaler. Till exempel, vid anv\u00e4ndning av neovim har inmatningsf\u00f6rdr\u00f6jningarna f\u00f6r terminalemulatorer baserade p\u00e5 VTE minskat till niv\u00e5n hos den snabbaste terminalen Alacritty. Specifikt i testet, relaterat till anv\u00e4ndning av verktyget «cat», minskade reaktionstiden vid nyckeltryckningar i Console och GNOME Terminal fr\u00e5n 40 till 12 ms, och i rullningstestet i neovim - fr\u00e5n 45 till 23 ms.

Prestanda\u00f6kningen vid anv\u00e4ndning av den nya versionen av VTE-biblioteket har ocks\u00e5 noterats i testupps\u00e4ttningen vtebench, som m\u00e4ter inte inmatningsf\u00f6rdr\u00f6jningar utan l\u00e4stid fr\u00e5n PTY-enheten och parserprestanda (testar rullnings- och musr\u00f6relsetider). I de flesta testerna \u00f6vertr\u00e4ffar Alacritty-terminalen Console och GNOME Terminal, men sistn\u00e4mndas avst\u00e5nd \u00e4r inte l\u00e4ngre s\u00e5 tydligt som tidigare. Dels f\u00f6rklaras GNOME Terminals avst\u00e5nd av overheadkostnaderna f\u00f6r att st\u00f6dja tillg\u00e4nglighetsverktyg.
