time to do some perf profiling

Why is your system load >5 with such little CPU usage? Seems like there is a lot of i/o on your system.

If it’s network traffic going over your VPN that could explain it.

Moonrise2473 OP ,

Because that’s a docker container on a “busy” server (mostly WordPress wasting cycles generating pages for some bots that really have to visit my blog over and over and over and over)

you might want to look into getting wordpress to generate static pages and only deliver the static html.

Overall using bloging tools that generate static pages is better than constantly requesting DB and dynamically compiling each page every time there is a request

Moonrise2473 OP ,

Yeah it’s a long time that I wanted to migrate to Hugo

The main issue is that a decade ago or so, I hosted a vibrant forum with the stupidest platform ever, bbpress. So my WordPress has something like 30k pages…

On my machine it’s consuming about 0.5% - 1.0% of cpu time, which is higher than zerotier in the same machine (almost zero).

Tailscale does a lot more things than just tunneling though. For example, on default installation it’ll catch all outbound dns request on the machine and route them through MagicDNS (100.100.100.100).

Moonrise2473 OP ,

That’s weird. I closed the docker on that specific machine (ryzen 5), copied the docker-compose directory (=same config) on an i5-6500T and now it’s using just 0.1% of CPU time.

Go back to ryzen and it’s 8% again 🤷

Isn’t CPU % is per thread?

One thing you could try doing if you feel up to it is to build Tailscale from source code. Often when built for your specific machine, performance improves.

I just checked my AMD box and tailscale there can consume ~15% of cpu time when the tunnel is under active use. When it’s not used it’s ~1.5%. But it’s a low power old AMD cpu though (AMD G-T56N), so I’m not use if it compares to Ryzen 5. On my intel machine, it’s ~5% when under active use, and idle at ~0.5%.

I use tailscale on my Ryzen system, and it always stays under 1% usage. Usually below 0.5%.
