got a new machine to work with GNUradio (all dependencies met, worked on a few other machines before just fine), yet it runs so slow that it's impossible to work with (especially FFTs). Did CPU benchmarks with 'hardinfo', and some of its benchmarks (blowfish, fibonacci,N-Queens, FFT) show minimal results, so I suspect some package and/or driver issue.
I'm on
5.19.0-46-generic
and hwinfo output for the CPU:
11th Gen Intel(R) Core(TM) i7-1165G7 @ 2.80GHz, 3622 MHz

Governor is set to performance via cpupower-gui, driver is intel_pstate.

So yeah, if anyone got ideas as to what might be the cause, it'd be much appreciated.
