Why is a "TeX point" slightly larger than an "American point"? There are many plain text files which were encoded in variant charsets. Effort that is cached either by your API service or other services it depends on will be served faster than effort that is not, and so youll see a bias toward faster response times. @mbuechmann will you tell me that is there any reference program from which I will under vegeta attack that how to implement it in go to test multiple routes.
