Extremely slow with antivirus

The company I work for requires that I run some horrible (but somehow popular) antivirus software on my PC which makes my eslint . take nearly 30 seconds to run on a very small project.

I did a little investigating and all of that slowness occurs in glob-util.js in the call to glob.sync(pattern, globOptions). If I modify globOptions to include ignore: 'node_modules/**' my linting drops to one second.

It appears that crawling node_modules causes my antivirus to kick in for each file, and I’m assuming I can’t be the only one with this problem. In any case, filtering out node_modules before the glob.sync call should certainly speed things up to some degree for everyone.

I understand that there is some complex logic involved with ignoring and unignoring paths so I see why all node_modules paths are included at this point in the code, but is there a chance this could be handled in some other way that would short-circuit the needless crawling? It would be a massive 99% speed increase, at least for me and anyone else in my position.

From the looks of it this could be a huge performance improvement. Provided nobody else wants to solve it in the near future, I’ll take a look at it until the end of the week.

This doesn’t solve my own problem, which is that the huge ignored directory is logs/, not node_modules/…
