Benchmark delivers weird results

[janriemer]

Hey @aswinkarthik,

when I run the benchmarks at https://github.com/aswinkarthik/csvdiff/tree/master/benchmark#go-benchmark-results I get the following weird results. It seems operations are optimized away!? Do you have any idea, why that is? NB: I am completely new to Go, so I might miss something here.
