vim-go uses github.com/mdempsky/gocode's -source parameter by default to provide a reliable use experience, but that comes at the cost of performance. If you'd like to disable the -source parameter, you can do so by using (see :help g:go_gocode_propose_source). Doing so will provide a faster experience, but you'll have to be sure to install the packages that you want to autocomplete on your own by using go install.
