Au fost publicate rezultatele evalu\u0103rii eficien\u021bei optimiz\u0103rilor ad\u0103ugate \u00een biblioteca VTE (Virtual Terminal library) \u0219i incluse \u00een versiunea GNOME 46. \u00cen timpul test\u0103rii, a fost m\u0103surat\u0103 reac\u021bia interfe\u021bei \u00een emulatorii de terminal Alacritty, Console (GTK 4), GNOME Terminal (GTK 3 \u0219i 4) \u0219i aplica\u021bia de testare VTE (un exemplu din depozitul VTE), fiind lansate \u00een Fedora 39 cu GNOME 45 \u0219i \u00een Fedora 40-beta cu GNOME 46. Aplica\u021bia Alacritty nu folose\u0219te biblioteca VTE \u0219i a fost aleas\u0103 ca etalon, deoarece, conform testelor anterioare, este unul dintre cei mai rapizi emulatori de terminale. Pentru m\u0103sur\u0103toare a fost folosit un senzor hardware bazat pe placa Teensy, care m\u0103soar\u0103 timpul dintre ap\u0103sarea butonului \u0219i apari\u021bia informa\u021biei pe ecran. <\/p>\n

Biblioteca VTE ofer\u0103 un widget GTK gata f\u0103cut, utilizat \u00een diverse emulatori de terminal pentru GNOME, printre care GNOME Terminal, Console, Black Box, Tilix, Terminator \u0219i Ptyxis. \u00cen versiunea GNOME 46, VTE a fost rescris semnificativ, ceea ce, conform evalu\u0103rilor dezvoltatorilor, a dus la accelerarea opera\u021biunilor, cu o cre\u0219tere a performan\u021bei care a ajuns p\u00e2n\u0103 la 40% \u00een teste. Din punct de vedere practic, optimiz\u0103rile au dus la reducerea \u00eent\u00e2rzierilor la redare \u00een configura\u021bii cu GTK 4. Anterior, \u00eent\u00e2rzierile la introducerea de date din tastatur\u0103 \u00een Console \u0219i GNOME Terminal erau evidente, ceea ce \u00eendep\u0103rta mul\u021bi utilizatori de la utilizarea emulatorilor de terminale nativi pentru GNOME. Odat\u0103 cu utilizarea versiunii VTE 0.76, aceast\u0103 problem\u0103 a fost rezolvat\u0103. <\/p>\n

Testarea independent\u0103 efectuat\u0103 a confirmat o reducere semnificativ\u0103 a \u00eent\u00e2rzierilor la introducerea datelor \u00een aplica\u021biile bazate pe VTE, care se observ\u0103 nu doar \u00een scenarii simple, ci \u0219i \u00een cele complexe de utilizare a terminalelor. De exemplu, atunci c\u00e2nd se folose\u0219te neovim, \u00eent\u00e2rzierile de introducere a emulatorilor de terminal bazate pe VTE au fost reduse la nivelul celui mai rapid terminal, Alacritty. \u00cen special, \u00een testul legat de utilizarea utilitarului «cat», reac\u021bia la ap\u0103sarea tastelor \u00een Console \u0219i GNOME Terminal a fost redus\u0103 de la 40 la 12 ms, iar \u00een testul de derulare \u00een neovim \u2014 de la 45 la 23 ms.

Accelerarea performan\u021bei \u00een utilizarea noii versiuni a bibliotecii VTE a fost de asemenea remarcat\u0103 \u00een setul de teste vtebench, care m\u0103soar\u0103 nu \u00eent\u00e2rzierile de introducere, ci timpul de citire din dispozitivul PTY \u0219i performan\u021ba analizei (teste de vitez\u0103 de derulare \u0219i de deplasare a cursorului). \u00cen majoritatea testelor vtebench, terminalul Alacritty dep\u0103\u0219e\u0219te Console \u0219i GNOME Terminal, dar decalajul celor din urm\u0103 nu mai este at\u00e2t de pronun\u021bat ca \u00eenainte. O parte din decalajul GNOME Terminal este explicat prin cheltuielile suplimentare de suport pentru persoanele cu dizabilit\u0103\u021bi (accesibilitate).
