There is only one where Go is 3 times slower, regex-dna. That would either be because of the speed of the regex implementation or the GC for the allocations.

There is only one where Go is 3 times slower, regex-dna. That would either be because of the speed of the regex implementation or the GC for the allocations. Apart from that Go is similar or twice as fast for reverse-component. Note that Go uses less memory for tasks that require memory to be allocated too. Go is doing better at the benchmarks game than it has in the past.
