Regarding loading of opened tabs on startup

hello, i created this topic to understand how opera manages memory. i have 2600+ tabs open. every time i start opera after a crash or after a shutdown, i disconnect the internet and opens it, lets it load (5-10 mins). then use unload extension to unload all the tabs(10-15 mins). now what i want to understand is that do i need to unload those tabs before reconnecting to the internet?
i recently connected to the internet then opened opera and only some (10-15 tabs) completely loaded and other tabs acted like they are unloaded but they showed up in unload tab extension as loaded so i am confused.
do opera unload tabs when it starts? or did it just try to load all those tabs and failed. another strange behavior is that when i have unloaded all the tabs, opera sometimes hogs a single core of my computer for a few minutes randomly. the tabs are already unloaded but it still uses cpu, task manager shows that it is the opera main process itself that uses it and not tabs. still very confused.

p.s. if i enrage anyone on the internet with the amount of tabs, sorry. they are all tabs i need open and there is not much of performance hit, it can be a 12 fps slideshow sometimes but it works perfectly fine for me.
