Onjiniyela besiphequluli se-Chrome mayelana nokwandisa izindlela zokulayisha ngokuvilapha kwezakhi zamakhasi ewebhu, okuvumela okuqukethwe ukuthi kungalayishwa ngaphandle kwendawo ebonakalayo kuze kube yilapho umsebenzisi eskrola ikhasi endaweni eyandulela isici. Ngaphambilini, ku-Chrome 76 nakuFirefox 75, le modi yayisivele isetshenziswe ezithombeni. Manje abathuthukisi be-Chrome bathathe isinyathelo esisodwa futhi bengeza amandla okulayisha amabhlogo we-iframe.
Ukulawula ukulayisha okuvilaphayo kwamakhasi, isibaluli "sokulayisha" sengezwe kumaka we-"iframe", angathatha inani elithi "vila" (defer loading), "ukulangazela" (layisha ngokushesha) kanye "nokuzenzakalelayo" (defer loading). ngokubona kwesiphequluli, uma imodi ivuliwe ). Kulindeleke ukuthi ukulayisha okuvilaphayo kuzonciphisa ukusetshenziswa kwenkumbulo, kunciphise ithrafikhi futhi kwandise isivinini sokuvula ikhasi lokuqala. Isibonelo, uma imodi entsha inikwe amandla, amabhulokhi anokukhangisa namawijethi e-Twitter, i-Facebook ne-YouTube ngeke asalayishwa ngokushesha uma engabonakali kumsebenzisi kuze kube yilapho umsebenzisi eskrola ikhasi endaweni ethile ngaphambi kwalokhu kuvinjelwa.
Ngokusho kwabathuthukisi, ngokwesilinganiso, ukulayisha okuvilaphayo kuzosindisa u-2-3% wethrafikhi, kunciphise inani ngo-1-2% futhi izokwehla ku-2%. Kumasayithi athile, izinguquko zibonakala kakhulu. Isibonelo, ukunika amandla ukulayisha okuvilaphayo kwebhulokhi ye-YouTube kuzonciphisa idatha elandiwe cishe ngo-500KB, i-Instagram ngo-100KB, i-Spotify ngo-500KB, ne-Facebook ngo-400KB. Ikakhulukazi, ukusetshenziswa kokulayisha okuvilapha kwamabhulokhi e-YouTube kuwebhusayithi ye-Chrome.com kwenze kwaba nokwenzeka ukunciphisa isikhathi esisithathayo ukuze amadivaysi eselula alinde ukuthi amakhasi atholakale ukuze aqale ukuxhumana ngemizuzwana eyi-10 futhi anciphise usayizi wefoni. iqale yalayisha ikhodi ye-JavaScript ngo-511KB.
