NodeBB slow after DB recovery

Solved Performance
1 1 634 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 That is quite the jump as importers from one forum platform to another are notoriously unreliable and could land up being quite costly if it requires managed services.

    @Panda said in Nodebb design: One negative is not being so good for SEO as more Server side rendered forums, if web crawlers dont run the JS to read the forum. From recollection, Google and Bing have the capability to read and process JS, although it’s not in the same manner as a physical person will consume content on a page. It will be seen as plain text, but will be indexed. However, it’s important to note that Yandex and Baidu will not render JS, although seeing as Google has a 90% share of the content available on the web in terms of indexing, this isn’t something you’ll likely lose sleep over. @Panda said in Nodebb design: The “write api” is preferred for server-to-server interactions. This is mostly based around overall security - you won’t typically want a client machine changing database elements or altering data. This is why you have “client-side” which could be DOM manipulation etc, and “server-side” which performs more complex operations as it can communicate directly with the database whereas the client cannot (and if it can, then you have a serious security flaw). Reading from the API is perfectly acceptable on the client-side, but not being able to write. A paradigm here would be something like SNMP. This protocol exists as a UDP (UDP is very efficient, as it is “fire and forget” and does not wait for a response like TCP does) based service which reads performance data from a remote source, thus enabling an application to parse that data for use in a monitoring application. In all cases, SNMP access should be “RO” (Read Only) and not RW (Read Write). It is completely feasible to assume complete control over a firewall for example by having RW access to SNMP and then exposing it to the entire internet with a weak passphrase. You wouldn’t do it (at least, I hope you wouldn’t) and the same ethic applies to server-side rendering and the execution of commands.

    @DownPW the ‘js’ code for the banner takes the time from the client, so what it displays really depends on the regional settings for the operating system. I’ve not seen this issue myself but would like to see some examples of screenshots if possible.
