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
I get this same behavior, except that my machine is not in any way slow
(except for intermittent issues with the secondary SATA controller on
the motherboard).
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?
I wouldn't think so; if nothing else, it doesn't always seem to settle
out to the same value every time.
Thanks all,
I'll ignore it :-)
Cheers,
Richard
