slows down dnsmasq server

[koenvdk]

I tried the cockpit tool on a host running dnsmasq in a docker container. It made that dns service (which my network relies on) extremely slow, so I had to remove cockpit again. It worked though, but strange that it would slow down the host that much, it was a 8cpu, 64g ram host.

@koenvdk Can you please write some more details, so that we have a chance to investigate and reproduce? For example:

• What's your host OS/version, and cockpit version?
• How did you start and configure the dnsmasq container?
• Does this slowness only happen when you are logged into cockpit, or merely by installing it? The latter would be a surprise, as installing cockpit only opens a systemd .socket unit -- nothing is actually running. And even when being logged into cockpit, there's nothing there that would directly touch dnsmasq.
• Anything interesting in the journal?

Thanks!
