OK

I think that's because ondemand changes the CPU frequency 10 times
less frequently than schedutil.

Writing a sufficiently large number to

/sys/devices/system/cpu/cpufreq/schedutil/rate_limit_us

when schedutil is the cpufreq governor may help, but I actually don't
know how large that number would need to be.
