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.
