Objavljeni su rezultati provjere u\u010dinkovitosti optimizacija dodanih u biblioteku VTE (Virtual Terminal Library) koje su uklju\u010dene u GNOME 46. Tijekom ispitivanja mjerena je odzivnost su\u010delja u terminalskim emulatorima Alacritty, Console (GTK 4), GNOME Terminal (GTK 3 i 4) i VTE Test App (primjer iz VTE repozitorija), pokrenutima na Fedora 39 s GNOME 45 i na Fedora 40-beta s GNOME 46. Alacritty ne koristi biblioteku VTE i odabrana je kao referenca, jer se, prema pro\u0161lim testovima, pokazala kao jedan od najbr\u017eih terminalskih emulatora. Za mjerenje je kori\u0161ten hardverski senzor temeljen na Teensy plo\u010di, koji mjeri vrijeme izme\u0111u pritiska tipke i pojave informacija na ekranu. <\/p>\n

Biblioteka VTE pru\u017ea gotov GTK widget koji se koristi u raznim terminalskim emulatorima za GNOME, me\u0111u kojima su GNOME Terminal, Console, Black Box, Tilix, Terminator i Ptyxis. U verziji GNOME 46 zna\u010dajno su revidirane unutarnje strukture u VTE, \u0161to, prema ocjenama programera, dovodi do ubrzanja operacija, pri \u010demu je dobitak performansi u testovima dostizao 40%. S prakti\u010dne strane, optimizacije su dovele do smanjenja latencija prilikom renderiranja u konfiguracijama s GTK 4. Ranije su latencije pri unosu s tipkovnice u Console i GNOME Terminal bile opipljive, \u0161to je mnoge korisnike odvratilo od kori\u0161tenja zadnjih terminalskih emulatora za GNOME. U kori\u0161tenju verzije VTE 0.76 ovaj problem je rije\u0161en. <\/p>\n

Nezavisno testiranje potvrdilo je zna\u010dajno smanjenje ka\u0161njenja unosa podataka u aplikacijama temeljenim na VTE, koje je primjetno ne samo u jednostavnim, ve\u0107 i u slo\u017eenim scenarijima kori\u0161tenja terminala. Na primjer, pri kori\u0161tenju neovim-a, ka\u0161njenje unosa emulatora terminala temeljenog na VTE smanjeno je na razinu najbr\u017eeg terminala Alacritty. Konkretno, u testu vezanom za kori\u0161tenje alata «cat», reakcija na pritisak tipki u Console i GNOME Terminal smanjila se s 40 na 12 ms, dok je u testu pomicanja u neovim-u do\u0161lo do smanjenja sa 45 na 23 ms.

Pobolj\u0161ano je najavljeno u testnom setu vtebench koji mjeri vrijeme \u010ditanja sa ure\u0111aja PTY i performanse parsiranja (testovi brzine skrolanja i pomicanja pokaziva\u010da), a nova verzija knji\u017enice VTE tako\u0111er pokazuje pobolj\u0161anje. U ve\u0107ini testova, Alacritty terminal nadma\u0161uje Console i GNOME Terminal, ali razlike s GNOME Terminal vi\u0161e nisu toliko izra\u017eene kao prije. Djelomi\u010dno je ka\u0161njenje GNOME Terminala obja\u0161njeno tro\u0161kovima podr\u0161ke za osobe s invaliditetom (pristupa\u010dnost).
