NodeBB slow after DB recovery

Solved Performance
1 1 806 1
  • 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…

    @cagatay The most reliable way to upgrade Node.js on Ubuntu depends on how you originally installed it. Method 1: Using NVM (Recommended) If you already use Node Version Manager (NVM), upgrading is simple. NVM allows you to keep both versions and switch between them if needed. Install Node 22: nvm install 22 Switch to Node 22: nvm use 22 Set it as your default: nvm alias default 22 Verify the change: node -v Method 2: Using NodeSource (PPA) If you installed Node.js via apt using the NodeSource repository, you need to update the repository script to point to the new version. Remove the old NodeSource list (optional but cleaner): sudo rm /etc/apt/sources.list.d/nodesource.list Download and run the NodeSource setup script for Node 22: curl -fsSL [https://deb.nodesource.com/setup_22.x](https://deb.nodesource.com/setup_22.x) | sudo -E bash - Install/Upgrade Node.js: sudo apt-get install -y nodejs Verify the installation: node -v Method 3: Using the ‘n’ Package If you have npm installed, you can use the n interactive manager. Clear the npm cache: sudo npm cache clean -f Install the ‘n’ helper: sudo npm install -g n Install Node 22: sudo n 22 Update your shell: hash -r Troubleshooting Permission Denied: If you see permission errors using Method 2 or 3, ensure you are using sudo. Path Issues: If node -v still shows version 20 after upgrading via NVM, restart your terminal or run source ~/.bashrc. Conflicts: Avoid mixing these methods. If you switch from apt to nvm, it is best to sudo apt remove nodejs first to avoid path conflicts.

    @Madchatthew said in TNG + Nodebb: you have to try and use duck tape and super glue to change something to make it do what you want it to do I couldn’t have put that better myself.

    @crazycells Agreed. It takes a more sensible approach. Nobody ever upvotes the first post - it’s usually much further down as the conversation progresses.

    @crazycells pleasure. Using percentages makes much more sense in this case. It’s the same argument with px vs pt vs em with fonts, margins, padding, etc., in the sense that em is generally preferred over px and pt https://stackoverflow.com/questions/609517/why-em-instead-of-px
