• Mysterious slowdown of Chrome

    From Stan Brown@21:1/5 to All on Thu May 16 11:33:56 2024
    This is a new problem around 9:45 this morning, after Chrome was
    working normally as late as 9:30. On my Windows 10 desktop, I clicked
    a link in an email from the New York Times to launch Chrome. On the
    tab I just get the "wait" spinner and "Loading". (The same link opens
    just fine on my Windows 11 laptop.)

    This occurs with one tab open, and any other link I try.

    Troubleshooting steps I tried:
    * It's only the Win 10 desktop: On my Windows 11 laptop, Chrome loads
    and runs normally.
    * Firefox on the Windows 10 desktop loads links normally. (I do jave
    Javascript turned off, so some sites don't work properly.)
    * Launching Chrome and trying to open a bookmark, in Task Manager I
    see 11 Chrome processes, 15.7% CPU usage, 233 MB memory use, 0%
    network use, and power usage "very high".
    * Resetting modem and router didn't help.
    * Windows Security ran earlier today and didn't find anything. I hit
    the Chrome three-dots menu and "About", and it did indeed do an
    update, but that didn't fix the problem.
    * Tried rebooting: no change in Chrome behavior.
    * A Malwarebytes scan found nothing.
    * In Chrome I hit Ctrl+Shift+Del and cleared the cache. No
    improvement.
    * Tried rebooting again, just in case. No improvement.

    Any suggestions of something else I should try, other than just
    dumping Chrome?

    Though I'm not certain, I think the Reading List feature may be the
    culprit.

    In Chrome, you can save (a link to) any Web page for later reading by right-clicking on a tab and selecting "Add Tab to Reading List". To
    access the saved reading list, hit the three-dots and select
    Bookmarks and Lists » Reading List. It takes almost no time to add
    something to the reading list, but considerably more time to read it
    and perhaps remove it, so the reading list tends to grow over time.

    On my Windows 11 laptop, which is synched to the problematic desktop
    via my Google account, I read and deleted maybe 20 items from the
    reading list, then tried Chrome on the Windows 10 desktop. Surprise!
    it seems to be working properly again.

    My hypothesis is that Google does some sort of prefetch on everything
    in the Reading List, insane though that seems, and I unknowingly
    exceeded some sort of hard limit. Or this could be a case of "post
    hoc ergo propter hoc", but anyway my problem seems to be solved, for
    now.

    I've had this happen a couple of times recently with Vivaldi, also a Chromium-based browser.
    IIRC, the first time I cleared the User Data\Default\IndexedDB, which, for me, had a couple of folders that pertained to the uBlock Origin extension.
    The second time, I believe I cleared the User Data\component_crx_cache and the User Data\GrShaderCache folder.
    I have no idea what's causing Bookmarks not to open, but in both cases, it did fix the problem.

    I don't use Chrome. However, something I'd look at is a difference in
    the suite of add-ons between Chrome and Firefox. Try using Chrome in
    its safe mode (no add-ons): load Chrome (without visiting a web site,
    just the about:blank page), and press Shift+Ctrl+I, More tools, start in
    safe mode. I think Ctrl+Shift+N also restarts Chrome in its safe mode.

    I couldn't find "open in safe mode" or similar under More Tools,
    either in regular user mode or in Developer Tools. I googled and
    found that Incognito Mode functions as safe mode. So it looks like
    the problem is one of my addins: Privacy Badger, uBlock Origin, and
    the Startpage search engine.

    I figured I could disable them one by one, so I began with uBlock
    Origin. But then I thought it would be worth seeing whether Chrome
    (or an addin) was hanging up in Javascript, so I turned it back on
    again. Sure enough, when I tried https://BrownMath.com/, which
    doesn't use Javascript, it popped up instantly. But ... so did links
    to sites that _do_ use Javascript. I'm puzzled.

    Alan mentions thinking that when he had a similar problem, deleting a Chrome\User Data\Default\indexedDB folder related to uBlock Origin
    solved the problem. I wonder if just disabling and re-enabling uBlock
    Origin fixed whatever was wrong. If so, I got lucky in starting with
    that one.

    Thanks, Alan. I do have the uBlock Origin extension, but among the

    uBlock Origin. Do you know what I'll be losing if I delete all those
    folders -- I'm guessing first-party cookies, so I may lose site
    settings and persistent logins?

    Hmm .. I know the problem began this morning, and only two subfolders
    are dated today: chrome-extension_cjpalhdlnbpafiamejdnhcphjbkeiagm_0.indexeddb.leveldb
    and
    https_developer.chrome.com_0.indexeddb.leveldb
    I'll bet the first one relates to uBlock Origin, because when I
    disabled and re-enabled that uBO a few minutes ago Chrome started
    working okay again. If the problem recurs I guess I'll try moving
    those two folders somewhere outside the Chrome hierarchy to see if
    that makes a difference.

    I don't seem to have either User Data\component_crx_cache or
    User Data\GrShaderCache .

    I know enough about the subfolders to know that those have nothing to do with cookies or site settings.

    You could always do a search for "Cookies" in the User Data folder.

    Are you using version 1.57.0 (Stable Build) of uBlock Origin?
    After I switched from the Development Build, located at https://chromewebstore.google.com/detail/ublock-origin-development/cgbcahbpdhpcegmbfconppldiemgcoii
    to the Stable Build at https://chromewebstore.google.com/detail/ublock-origin/cjpalhdlnbpafiamejdnhcphjbkeiagm,
    I haven't had the Bookmarks problem again.
    That may just be a coincidence.

    I don't seem to have either User Data\component_crx_cache or
    User Data\GrShaderCache .

    I thought that they were common to all Chromium-based browsers.

    I think it must have been. I have 1.57.0 on both the Windows 10
    desktop that had the problem and the Windows 11 laptop that didn't. I
    can't remember when I updated, but certainly it was well before the
    problem manifested.
