NodeBB slow after DB recovery

Solved Performance
  • One thing I noticed was that after recovering the assets and database onto a test server: (see below)

    https://sudonix.com/topic/239/testing-out-webdock-io

    The performance of the replica NodeBB install was painfully slow. After much searching and hair pulling, I found that the indexes seemed to be missing - a point which is referenced by NodeBB themselves here

    https://community.nodebb.org/topic/11299/slow-page-loading-on-digitalocean/12?_=1646060175987

    When I checked /api/recent it was indeed slow - like a snail. So, at their suggestion, I opened up mongodb and added the missing indexes

    db.objects.createIndex({ _key: 1, score: -1 }, { background: true });
    db.objects.createIndex({ _key: 1, value: -1 }, { background: true, unique: true, sparse: true });
    db.objects.createIndex({ expireAt: 1 }, { expireAfterSeconds: 0, background: true });
    

    The difference is quite astonishing. Now it runs like the Ferrari I’ve come to love and respect ♥

    Might be useful for someone else in the same boat…

    @DownPW it’s your only realistic option at this stage.

    @Panda you’d be surprised. If you consider that you’d need to use the API to be able to populate a WordPress widget for example (which in turn would of course be PHP), taking this route is still immensely popular.

    @Panda as, yes, now I understand and that makes 100% sense. It means those who get down voted can still have an opinion and use common services.

    And yes, you’re right. Rather than down vote, just ignore if you don’t agree.

    Seems to be better with some scaling fix for redis on redis.conf. I haven’t seen the message yet since the changes I made

    # I increase it to the value of /proc/sys/net/core/somaxconn tcp-backlog 4096 # I'm uncommenting because it can slow down Redis. Uncommented by default !!!!!!!!!!!!!!!!!!! #save 900 1 #save 300 10 #save 60 10000

    If you have other Redis optimizations. I take all your advice

    @eveh It’s not a GIF, no. It’s actually a webp file so made much smaller, and uses keyframes to control the rotation on hover. You can easily make your own though 🙂

    The CSS for that is as below

    @keyframes rotate180 { from { transform: rotate(0deg); } to { transform: rotate(180deg); } } @keyframes rotate0 { from { transform: rotate(180deg); } to { transform: rotate(0deg); } }

    Your milage may vary on the CSS below, as it’s custom for Sudonix, but this is the class that is used to control the rotate

    .header .forum-logo, img.forum-logo.head { max-height: 50px; width: auto; height: 30px; margin-top: 9px; max-width: 150px; min-width: 32px; display: inline-block; animation-name: rotate180, rotate0; animation-duration: 1000ms; animation-delay: 0s, 1000ms; animation-iteration-count: 1; animation-timing-function: linear; transition: transform 1000ms ease-in-out; }

    I find the problem Mark 😉

    The error message indicated this path :

    http://localhost:4567/assets/plugins/nodebb-plugin-emoji/emoji/styles.css?v=6983dobg16u

    I change the path url on config.json

    47bacc80-f141-41e4-a261-3f8d650cc6f6-image.png

    And all it’s good 🙂

    Weird, I didn’t have to change that path before 1.19.3

    But this does not prevent the problem from a clean install with Emoji Plugin

    EDIT: After test, that resolv the problem installation for 1.18.x but not for 1.19.x (I have other error message when I run ./nodebb Setup

    For resume: NodeJS 16_x with 1.18.x is ok
