I noticed that the performance of the sublime plugin is quite often "slow" and does not display the typed text until gocode has fetched the results. In the example do i try to write a word as fast as plausible (for ex. http) the first letter will show at once but the rest will follow once gocode is done.

I didn't write the Sublime plugin, and I don't have the bandwidth to investigate this. If you'd be willing to debug this, I'm happy to accept PRs. Some alternative options you could investigate:

• filing an issue at nsf/gocode - it's a bigger repository, and even though it's unmaintained, someone might see the issue and fix it
• using GoSublime - it forks all of gocode into the repository, but it would probably be possible to hack together a version that forks this version

I suspect it has to do that all the requests are preformed over a single thread. I will try to investigate the issue and create a PR if i succeed.
