Abaphuhlisi besiphequluli seChrome malunga nokwandisa iindlela zokulayisha ukonqena kwezinto zamaphepha ewebhu, ukuvumela umxholo ukuba ungalayishwa ongaphandle kwendawo ebonakalayo de umsebenzisi askrole iphepha kwindawo ngokukhawuleza eyandulela into. Ngaphambili, kwiChrome 76 kunye neFirefox 75, le mowudi yayisele iphunyeziwe kwimifanekiso. Ngoku abaphuhlisi be-Chrome bathathe inyathelo elinye kwaye bongeza ukukwazi ukulayisha iibhloko ze-iframe.
Ukulawula ukulayishwa kobuvila kwamaphepha, uphawu "lokulayisha" longezwe kwithegi ethi "iframe", engathatha ixabiso elithi "lazy" (defer loading), "ulangazelelo" (umthwalo ngokukhawuleza) kunye ne "auto" (defer loading). ngokwengqiqo yesikhangeli, xa imowudi yenziwe yasebenza ). Kulindeleke ukuba ukulayisha okuvila kuya kunciphisa ukusetyenziswa kwememori, ukunciphisa i-traffic kunye nokwandisa isantya sokuvulwa kwekhasi lokuqala. Ngokomzekelo, xa imowudi entsha ivuliwe, iibhloko ezineentengiso kunye neewijethi ze-Twitter, i-Facebook kunye ne-YouTube aziyi kuphinda zilayishwe ngokukhawuleza ukuba zingabonakali kumsebenzisi de kube umsebenzisi upheqa iphepha kwindawo phambi kwezi bhloko.
Ngokutsho kwabaphuhlisi, ngokomyinge, ukulayishwa kovila kuya kusindisa i-2-3% yezithuthi, ukunciphisa inani nge-1-2% kwaye iya kunciphisa kwi-2%. Kwiindawo ezithile, utshintsho lubonakala ngakumbi. Umzekelo, ukuvumela ukulayishwa kobuvila kwebhlokhi yeYouTube kuya kunciphisa idatha ekhutshelweyo malunga ne-500KB, i-Instagram nge-100KB, iSpotify nge-500KB, kunye ne-Facebook nge-400KB. Ngokukodwa, ukusetyenziswa kokulayisha ukonqena kweebhloko zeYouTube kwiwebhusayithi yeChrome.com kwenze ukuba kube lula ukunciphisa ixesha elithathayo ukuba izixhobo eziphathwayo zilinde ukuba amaphepha afumaneke ukuze aqalise ukusebenzisana ukuya kuthi ga kwimizuzwana eyi-10 kwaye anciphise ubungakanani besixhobo. iqale yalayisha ikhowudi yeJavaScript nge511KB.
