Create / Update pages slow performance?

[tobidemski]

Hey guys,

im new to wikijs and i like it so far but im facing a problem(?) about updating / saving pages and the performance.
If I'm creating / saving a page its takes a bit till the page is saved. The page does not contain any content (just a dot for the test). Is this a normal behavior or is there a perfomance bug?

Container log after clicking "save page":
Loading configuration from /wiki/config.yml... OK
2021-09-13T20:43:12.871Z [JOB] info: Rendering page ID 6...
2021-09-13T20:43:14.247Z [JOB] info: Using database driver pg for postgres [ OK ]
2021-09-13T20:43:17.018Z [JOB] info: Rendering page ID 6: [ COMPLETED ]

CPU increases while saving the page + ~20%

Current wikijs stats
Total pages: 5
Total users: 2
Total groups: 3
Almost all default settings.

Current env stats
wikijs: 2.5.214
PostgreSQL: 11.13
Node.js: 14.17.6
Type: docker
Host: Synology DS916+
Total CPU load on NAS: ~7%
Total RAM load on NAS: 53%

This is also something I immediately wondered, editing pages is pretty sluggish at the moment, even on an install with just a few pages....

Ahhh, it looks like tasks like rendering pages fork a child process per request.

This is a lot of overhead for a web request (which ideally should complete in under 250ms), and something that can be resolved by doing the forking on initialization and submitting to a pool. See https://www.alexanderlolis.com/node-js-fork-is-slow-deal-with-it

This is being addressed in the upcoming 3.0 version.
