Slow start up / resetting on startup

wisemandenny commented 4 years ago

Describe the bug When I open a new zsh shell, it takes around 2 seconds to start. There is strange behavior as well: it loads the zsh prompt, then the prompt disappears and reappears after a short delay. This makes zsh pretty hard to use. I have included a video and the output from zsh/zprof.

Further, when this new shell does finally appear, it takes quite a long time for the prompt to become interactive. You can see this in the video before "zshzshzhszhshzshzs" appears. (I am typing zsh repeatedly before the prompt becomes interactive).

To Reproduce Any time I run ZSH.

Expected behavior Shouldn't take so long too load, definitely shouldn't "refresh".

 - OS: Windows 10 2004
- Running WSL2 with Ubuntu 20.04

update: i reinstalled ubuntu, zsh, and black-void. The startup time is greatly reduced, but still it is "refreshing".

Performance

Start Time: It's made with some care, but if IO is slow, it can cause problems (not SSD, VM, WSL).
Interactive: This is because the prompt is designed to be visible first during loading. It takes a lot of effort to further reduce the current start time.

Refesh(Flickering) It doesn't happen on native Linux. I think it should install WSL to find out.

Found a fix for this, thought it might be a good idea to include it in the README.

Reflected in Wiki:Error and specified in README.

Thank you for finding a good solution.
