Google Njira yovomerezeka ya Chrome Kutsekereza zotsatsa zomwe zimapangitsa kuti pakhale katundu wambiri pa CPU kapena kutsitsa magalimoto ambiri. Ngati malire ena apitilira, zoletsa zotsatsa za iframe zomwe zimawononga zinthu zambiri zitha kuzimitsidwa.
Zikudziwika kuti mitundu ina ya malonda, chifukwa cha kukhazikitsidwa kwa code kosagwira ntchito kapena ntchito yowonongeka mwadala, imapanga katundu wambiri pa machitidwe a wogwiritsa ntchito, kuchepetsa kutsitsa kwazinthu zazikulu, kuchepetsa moyo wa batri ndi kuwononga magalimoto pa mapulani opanda malire opanda malire. Zitsanzo zodziwika bwino zamagawo otsatsa omwe amayenera kuletsedwa ndi monga zoyika zotsatsa zokhala ndi code ya cryptocurrency mining, mapurosesa akulu osakanizidwa zithunzi, ma decoder amakanema a JavaScript, kapena zolemba zomwe zimakonza zochitika zowerengera nthawi (mwachitsanzo, zowukira zam'mbali).
kachidindo block ngati yawononga masekondi opitilira 60 a nthawi ya CPU mu ulusi waukulu wonse kapena masekondi 15 pakapita mphindi 30 (imagwiritsa ntchito 50% yazinthu zopitilira masekondi 30). Kuletsa kudzayambikanso gawo lotsatsa likatsitsa deta yopitilira 4 MB pa netiweki. Kuti athetse kugwiritsa ntchito kutsekereza ngati chizindikiro cha kuwukira kwam'mbali, komwe kungagwiritsidwe ntchito kuweruza mphamvu ya CPU, akufunsidwa kuti awonjezere kusinthasintha kwapang'onopang'ono pazotsatira ndikuletsa kuyambitsa.
Zotsatsa zokha zomwe wogwiritsa ntchito sanagwirizane nazo zidzatsitsidwa ndikusinthidwa ndi chenjezo loletsa. Kulumikizana pakati pa iframe ndi kutsatsa kumatsimikiziridwa mwanzeru pogwiritsa ntchito makina omwe alipo . Makhalidwe a Threshold adasankhidwa kuti alole zochitika za 99.9% zamagawo otsatiridwa kuti zidutse. Zikunenedweratu kuti njira yotsekereza yomwe ikuyembekezeredwa idzachepetsa kuchuluka kwa magalimoto kuchokera kumagulu otsatsa ndi 12.8% ndikuchepetsa kuchuluka kwa CPU ndi 16.1%.
