[$] Comparing BPF performance between implementations

Alan Jowett returned for a second remote presentation at the 2024Linux Storage,Filesystem, Memory Management, and BPF Summit to compare the performance ofdifferent BPF runtimes. He showed the results of the MIT-licensed BPFmicrobenchmark suite he has been working on.The benchmark suite does not yet provide a good direct comparison between allplatforms, so the results should betaken with a grain of salt. They doseem to indicate that there is some significant variation betweenimplementations, especially for different types of BPF maps.
