People have been devastated by this for years and it seems all that anyone says is "they share resources - that's why it's so fast" or such. There has GOT to be a better answer. It's been too many years of this making excuses. If nothing else, can't someone develop JUST a rinky dinky program/add-in that loops through all open pages one by one, closing, pausing while we check Taskman, then reopening so we can see the effect? That would be TRIVIAL for someone to write just that crude thing. But it would save people breathtaking amounts of time because we're having to do this manually, over and over and over and over and over. Even with this simple routine, it could be enhanced to record the CPU load from Taskman or TaskInfo or something, since we'd be slowly, ploddingly writing down or pasting the results as I stepped through the pages one by one. Better yet, ideally, just do this, which also should not be technically difficult - seriously. Take some unused field and populate it with identifying information (like the Save As name of the page), then inform Microsoft (for taskman, resmon) and Iars (for TaskInfo) where it is. Or write our own CPU monitor extract just to measure FX CPU, that displays which PID goes with which window)(s). THAT'S WHAT IS DESPERATELY NEEDED. An indication of which browser instances go with which PIDs. Even if there's some overlap, if PID 6632 is using an entire core and more of my desktop, if I can just even partially limit which browser windows are burning there, that would be enormous. <pre>For example PID....FX-ID 15......google.com / (name of page, e.g. "power supplies - Google Search.htm") 15......mozilla.com / (name of page, ... 15.....microsoft.com / (name of page, ... 15.....youtube.com / (name of page, ... 15.....youtube.com / (name of page, ... 15.....youtube.com / (name of page, ... 15.....youtube.com / (name of page, ... 25......google.com / (name of page, e.g. "power supplies - Google Search.htm") 25.....microsoft.com / (name of page, ... 33.....ameritrade.com / (name of page, ... 33.....yahoo.finance / (name of page, ... 33.....youtube.com / (name of page, ... 33.....youtube.com / (name of page, ... 33.....youtube.com / (name of page, ... 33.....youtube.com / (name of page, ... 33.....goduckgo.com / (name of page, ... etc.</pre> If the reason no one's done this is because there's more than one page associated with each PID, that's covered in the listing above. Just list what you know, every one of them. Do you see how powerful that would be, if we knew that PID 15 was shredding the CPU, and we could at least limit it to a limited number of possible criminal pages? I keep numerous windows open and like it or not the reality is that one or more of them are running obscenely rude loops to refresh the page or scan for input or whatever. I have a very well equipped desktop but it is hammered by one or more such sites. I and I am sure others have wasted hours and hours and hours hunting and pecking to diagnose this, and there's NO END to it, because there will continue to be piss poor webpages that suck CPU and disk. Even from microsoft.com, as you surely know to be often the worst performers of all. I use NoScript but that is not perfect; you have to continuously adjust it for different sites, and you don't know WHICH sites need to be throttled down. It's wildly inefficient when we're shooting in the dark, because we DON'T KNOW WHICH BROWSER WINDOW is the jerkoff. BTW I have many WINDOWS open - almost never tabs. It is almost always massively more efficient than using tabs when you have many. Namely, with windows I can use Windows' own alt-tab, or click or hover the taskbar to navigate. I volunteer a lot of my time, a lot, both in technical areas and in personal charity. I'd do this myself, but I have no browser or HTML development background. Can't someone please come up with something? Asking for the millionth time, please? Sorry I'm getting nasty but there's all this senseless massive waste of time, and it will never go away - unless you heroically answer the call.
