Slow startup

[sindresorhus]

There's a noticeable deadtime after activating the generator system before the prompt is shown, often more than 5 seconds. Probably has something to do with the search paths.

This is can be annoying and should be improved.

For me it's more than a minute. Are there any debugging steps to figure out why it takes that long? I ran strace on it, which shows it stalling on a number of epoll_wait(3, {}, 64, 0) calls. I'm on 64-bit Linux.

I never got this issue myself. The only thing I can think of that can cause this is the globbing done when looking for generators in your workspace.

Please, provide a test case and something we can reproduce and test so that I can work on improving that.

@mklabs Testcase: yo webapp

[mklabs]

Okay, so I can confirm that. That's something I never experimented myself, and I did run a few yo webapp .. Let me try to reproduce, must be something silly.

[sindresorhus]

@addyosmani can also confirm the slowdown.

FWIW I should have mentioned I was using release 0.9.6.

@passy @btford if you have time, could you verify whether you're also able to repro this? We can spend some time on optimization but I'd like to make sure this is still an issue first if possible.

[sindresorhus]

@kevva if you would be interested in looking into how we can optimize the generator system.

[kevva]

Will do.

[sindresorhus]

@kevva @passy @sindresorhus we should do a sweep and see if there is anything (in addition to lazy loading) we can do to improve startup and general speed.
