Suggestions on what to do to improve performance

[jansensan]

Question or comment

My site's Node process seems to "idle" at 25% when there are no visitors, and 75%+ when there are. mongod seems steady at 20% all the time:

There is likely some work that could be done on my part to improve Apos' performance no? I am uncertain what to take into consideration, so that's why I am asking here.

Details

Version of Apostrophe:
Apos v2.223.1

Version of Node.js:
v16

Server Operating System:
Ubuntu 18.04.4 LTS (GNU/Linux 4.15.0-197-generic x86_64)

I haven't seen this behavior. For context, how much RAM and how many CPU cores does this server have?

[jansensan]

2 GB Memory, 50 GB Disk. From the image name I would believe a single CPU core.

OK, that should generally be adequate.

Apostrophe doesn't typically do this when there is no traffic, no. I usually see zero load on Node.js in the absence of traffic. I would look at whether you have any custom Node.js code that does extra work, for instance on an interval timer.
