Currently on latest firefox and those 20 tabs are using 22-26% CPU and 11,000MB memory.
Running ublock yes, majority of tabs are constantly refreshing with new price action - not sure if that makes much of a difference, i guess the page isnt just loaded and then static
Will try playing around with PBO
Wont be network related, running Cat7 cables in the house to my wifi6 router, im the only one using the internet
Thanks
