A large number of issues on an open source server are people wondering why perf is so bad when they give it a single core. Single core performance hasn’t improved much in the last 10-15 years, but more and more of them can be accessed. It blows me away how expensive they are that people need to worry about it.

Intel's single core performance has 3.4xed in 15 years (980X vs 285K)

Single core perf doubled every 8 years, multicore every 6 years, and GPUs every 3 years !

What evidence are you using for that single core claim?

In 8 years, Ryzen went from 1166 geekbench 6 single core to 3398.

Single core performance isn't just clock frequency. It must be multiplied by average IPC, but really it's more difficult since you have to account for factors like new SIMD instructions. Effective IPC improvements are where a significant fraction of single core speedup came from in this period
