getting crazy slow planck startup after upgrading to 2, I'm sure it's not planck itself but something in my environment, but anyone have any ideas how to track down?

@bfabry Try planck -X -d to see startup timing. Is it lengthy to get the REPL running?

What do you get for time planck -e1?

Wow. 16 seconds...

haha right

What OS?

yosemite 10.10.5

I'm a bit of an "I'll update OSX when I get a new laptop" guy, OSX upgrades just always seem to go badly

I can see if I can repro. I have access to a VM running that, and a physical box running Mavericks.

Did you install using brew install --devel planck?

I did

Do you have the Safari preview installed?

(This might cause a different JavaScriptCore to be used.)

safari looks to be 10.0.2

OK. firing up my Yosemite VM now.

maybe I should just try and upgrade... ugh, but it'll definitely kill my env and eat a day

No… 16-second startup is definitely not caused by an older OS. Something really odd is going on IMHO.

I’m getting curl complaining on Yosemite about SSL… gonna see if I can figure that out

@bfabry I failed to repro on Yosemite. I’ve opened a ticket where we can add info https://github.com/mfikes/planck/issues/431

@bfabry It would be interesting to know what timings you are getting near the end of the -X output. I’m wondering if it is blocking excessively long waiting for the “engine ready” event. Here is what I see:

Thanks. That looks normal. 1.6 seconds to init JSC
