If it is more memory efficient, why do we only get benchmarks on speed? Allocations not the same as memory usage

[Gleb Minaev]

Looks interesting! But how did you measure the performance? Especially the allocations.

@Todd Sorry, I could miss it. But I already read the article and didn't find neither any description of benchmarking process nor argument why memory performance is determined by number of memory allocations.
