Clojurians Log v2

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
