i optimized to 30% usage i think. instead of 5 instances on medium i have 3 on fast speed.
also cache after few hours of constant browsing could add to CPU i think, not sure how though but i saw huge increase in cpu usage after a day. incognito mode also could add to CPU quite instantly so i disabled incognito. because incognito doesnt read nor store cache afaik so if you browse similar websites then it will always be processed again, i am not sure if thats how it works though but i really saw cpu increase on incognito
i installed cache plugin that resets cache when LOOP iteration == 10 and then it restarts these three instances.
now much better though it can sometimes get to 35% on 3 instances only. i guess its just chrome taking so much cpu. coming from other automation programs - they used either firefox or chrome but werent so cpu intensive so they probably used more barebone version or strongly limited it.
i am not doing anything heavy on bot, just loading website, saving text to csv, repeat
anyway kantu is the only browser automation software that i managed to get browser extensions on so its all good.
i decided to enable hardware acceleration, uses a bit less cpu now. but i had to test because some people report it uses more.
I use an old version of Kantu and i must use an alternative to xrun command because latest kantu for firefox take 100% of my cpu and usually xmodules it is not always detected.
Here my firefox with kantu 5.2.3 totally stucked i downgrade to kantu 5.1.9
