MEMORY LEAK after cumulative updates?

    I have an older PC with 4GB of RAM. I just checked my free memory and it was 10 MB. FF open and two forum tabs.
    My PC runs like a Swiss watch with 4GB Ram Win 10 Pro. I've never, ever had any operational problems.
    I wouldn't get to hung up on too much on the amount of standby memory. Standby is just cached memory, and should you open a new app Windows will release some of the cached memory to run the app. Windows will use all of the memory it can and throttle back standby memory as required. Ram is installed and meant to be fully utilized for best performance. Unused RAM is useless. Just my opinion!
    I bet your PC is running just fine too. The attachment will blow you away. At he bottom of your Resource page, hover your mouse over Available, Cached,Total and Installed. Windows will give you a complete explanation of how it's handling your resources.

    I'm leaning towards my original gut feeling of recent system updates. I know that standby RAM in certain circumstances always disappeared (running Defender, video conversion, etc) but the general usage thing has decreased. Meaning that standby RAM, in general, goes away faster now.

    Rollback (uninstall) the 2 recent KBs and block them with WUMT. See what that shows you and your gut.

    When I was in the Mac world I heard the same notion regarding compressed memory. I understand what you're saying but it isn't entirely true.

    You have to understand I'm not hung up on standby ram. What I'm sharing is that there are performances issues related to standby RAM being maxxed out. Different topic.

    What happens is I'll be typing (on a board just like this) and suddenly realize I'm typing faster than the words are appearing. On an i5 SSD with 8GBs of RAM and not much open? That's a minor but definite operational problem.

    Just before I wrote these words I noticed my pointer was behind itself. Dragging instead of gliding. What was the FIRST thing I did? Open up resource monitor and this is what I found --

    Actually it was maxxed out entirely when I looked, but this is close enough. Look at how little is open in the taskbar. The problem is I have Chrome running YouTubeTV and Firefox sitting on other tabs.

    Where you say it's normal for an OS to use the RAM that is there, sure, fine, but that's beside the point. My point is that when the system does this it slows down. In my case a laggy pointer or laggy text. The only fix is to quit apps and reboot, or use that app that frees up the standby memory.

    And, again, my overall point is that in recent updates this memory management has become weaker. One of the last two triggered it. I'm not imagining this. It's a minor but definite change towards the annoying.

    Thanks but me and my gut aren't in the mood to risk rollbacks. I'd rather wait and see if new cumulative updates repair this.

    Try moving FF cache to RAM instead of disk.

    Here is Firefox Quantum with three tabs open on my machine:

    I suppose that I should state that I clean installed Firefox this time.

    Callender, did you add that setting, "browser.cache.memory.capacity" to your browser? I don't have that setting in my about:config.

    By the way, this is why I asked... As you can see, I have a 6 gig machine but only about 300 megs between standby and free. I pretty much stay this way with FF open because I do have a lot of tabs that stay open. I know I need a machine with more ram (my laptop is maxed) but until then, what's the best way to handle this phenomenon?

    Also, my page file is 2.5 gigs and handled by windows and man can you see my drive maxing out from time to time. I know it's just the page file since my memory stays about maxed.

    Just to be clear... this is not "memory leak"... it's just allocated memory the app components set aside and used when those components are instantiated. I don't have knowledge of the inner workings of FF but I would think add-ons will contribute greatly to this....

    I do not, either. FF 62 Stable (x64). Notice @Callender is running 32-bit. Does this matter?

    Yes I did add it. Bitness does not matter.
