Hi all,
I see messages like this frequently for a day or two after rebooting a
particularly slow old machine (Atom-based HP thin client, running as an
OpenVPN endpoint):
May 23 05:36:37 ovpn kernel: [14268.392418] perf: interrupt took too
long (4020 > 3996), lowering kernel.perf_event_max_sample_rate to 49750
Would it be a good idea to set this value at boot time, rather than
waiting for it to auto-adjust down till it settles?
Actually I don't know if it's because the machine is slow; it's just the
only machine I see this on.
At the time I've looked at this, I came to the conclusion that a cure
was worse than the illness.
