Editor is taking 2 to 3 seconds to re-lint

[jeyanthimuthuram]

I saw the discussion about enable linting while typing , I feel that is much needed and related to here.

Because whenever I am saving only the python plugin is re-linting and it takes around 2 to 3 seconds that is I feel slow , because I need to wait two to three second to check I did correct or not ?

Currently there is little we can do about this. We just run PyLint and it is not very fast. It also works on files so they need to be saved. This is a major work item since it requires replacement of at least some of pyling functionality.

Folding into #444

Couldn't this be improved by running pylint inside a server similar to the one used by Jedi and selectively invalidating the astroid cache for newly saved files?
