买了一台新机器来运行 GNUradio（满足所有依赖性，之前在其他几台机器上运行得很好），但它运行速度太慢，根本无法运行（尤其是 FFT）。使用“hardinfo”进行了 CPU 基准测试，它的一些基准测试（blowfish、fibonacci、N-Queens、FFT）显示结果很少，所以我怀疑是某些软件包和/或驱动程序的问题。
我上线了
5.19.0-46-generic
以及 CPU 的 hwinfo 输出：
11th Gen Intel(R) Core(TM) i7-1165G7 @ 2.80GHz, 3622 MHz
11th Gen Intel(R) Core(TM) i7-1165G7 @ 2.80GHz, 3825 MHz

11th Gen Intel(R) Core(TM) i7-1165G7 @ 2.80GHz, 4208 MHz
11th Gen Intel(R) Core(TM) i7-1165G7 @ 2.80GHz, 3911 MHz

11th Gen Intel(R) Core(TM) i7-1165G7 @ 2.80GHz, 4093 MHz
调节器通过 cpupower-gui 设置为性能，驱动程序是 intel_pstate。

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