Performance issue #20

Open pavelloz opened 4 years ago

pavelloz commented 4 years ago

It looks like server is taking far too much CPU than it should.

I use chokidar regularly on projects with more files than this one and it doesnt hug nearly as much cpu.

Setting exts to only one extension (ie. erb) didnt help.

OS: macOS 10.14.6

I just run a test with native livereload straight from npm, and it doesnt have this issue:

livereload . -e "erb,js,css"

Having the same issue and makes it nearly impossible to use without putting on the headphones and not complaining about the fan noise (400% CPU). The high CPU usage also stops immediately after disabling the LiveReload server

Made an update to the chokidar package (used internally for file watching) and after this the CPU-performance was normal again.

I made a Pull Request to update the dependency, if anyone needs a fix until a new version is released, you can download a Prerelease here: https://github.com/ofhouse/livereload-vscode/releases/tag/v0.3.0-rc.0
