Les r\u00e9sultats de l'\u00e9valuation de l'efficacit\u00e9 des optimisations ajout\u00e9es \u00e0 la biblioth\u00e8que VTE (Virtual Terminal library) et int\u00e9gr\u00e9es dans la version de GNOME 46 ont \u00e9t\u00e9 publi\u00e9s. Lors des tests, la r\u00e9activit\u00e9 de l'interface a \u00e9t\u00e9 mesur\u00e9e dans les \u00e9mulateurs de terminal Alacritty, Console (GTK 4), GNOME Terminal (GTK 3 et 4) et VTE Test App (un exemple du d\u00e9p\u00f4t VTE), en les ex\u00e9cutant sur Fedora 39 avec GNOME 45 et sur Fedora 40-beta avec GNOME 46. L'application Alacritty n'utilise pas la biblioth\u00e8que VTE et a \u00e9t\u00e9 choisie comme r\u00e9f\u00e9rence, car, selon les tests pr\u00e9c\u00e9dents, elle est l'un des \u00e9mulateurs de terminal les plus rapides. Un capteur mat\u00e9riel bas\u00e9 sur une carte Teensy a \u00e9t\u00e9 utilis\u00e9 pour mesurer le temps entre l'appui sur le bouton et l'apparition des informations \u00e0 l'\u00e9cran. <\/p>\n

La biblioth\u00e8que VTE offre un widget GTK pr\u00eat \u00e0 l'emploi, utilis\u00e9 dans divers \u00e9mulateurs de terminal pour GNOME, parmi lesquels GNOME Terminal, Console, Black Box, Tilix, Terminator et Ptyxis. Dans la version de GNOME 46, les structures internes de VTE ont \u00e9t\u00e9 consid\u00e9rablement retravaill\u00e9es, ce qui, selon les d\u00e9veloppeurs, a entra\u00een\u00e9 une acc\u00e9l\u00e9ration des op\u00e9rations, dont la performance a atteint dans les tests jusqu'\u00e0 40%. D'un point de vue pratique, les optimisations ont permis de r\u00e9duire les d\u00e9lais de rendu dans les configurations avec GTK 4. Auparavant, les d\u00e9lais de saisie au clavier dans Console et GNOME Terminal \u00e9taient perceptibles, ce qui rebutait de nombreux utilisateurs d'utiliser les \u00e9mulateurs de terminal par d\u00e9faut pour GNOME. Avec la version VTE 0.76, ce probl\u00e8me a \u00e9t\u00e9 r\u00e9solu. <\/p>\n

Des tests ind\u00e9pendants ont confirm\u00e9 une r\u00e9duction significative des latences d'entr\u00e9e dans les applications bas\u00e9es sur VTE, observable non seulement dans des sc\u00e9narios simples, mais aussi dans des situations complexes d'utilisation des terminaux. Par exemple, lors de l'utilisation de neovim, les latences d'entr\u00e9e des \u00e9mulateurs de terminal bas\u00e9s sur VTE ont \u00e9t\u00e9 r\u00e9duites au niveau du terminal le plus rapide, Alacritty. En particulier, dans le test li\u00e9 \u00e0 l'utilisation de l'outil \u00ab cat \u00bb, le temps de r\u00e9ponse aux frappes de touches dans Console et GNOME Terminal est pass\u00e9 de 40 \u00e0 12 ms, tandis que dans le test de d\u00e9filement dans neovim, il est pass\u00e9 de 45 \u00e0 23 ms.

L'acc\u00e9l\u00e9ration des performances avec la nouvelle version de la biblioth\u00e8que VTE a \u00e9galement \u00e9t\u00e9 not\u00e9e dans l'ensemble de tests vtebench, qui mesure non pas les latences d'entr\u00e9e, mais le temps de lecture depuis l'appareil PTY et les performances d'analyse (tests de vitesse de d\u00e9filement et de d\u00e9placement du curseur). Dans la plupart des tests, le terminal Alacritty surpasse Console et GNOME Terminal, mais l'\u00e9cart des derniers n'est plus aussi marqu\u00e9 qu'auparavant. En partie, le retard de GNOME Terminal s'explique par les co\u00fbts d'assistance aux personnes handicap\u00e9es (accessibilit\u00e9).
