I've commented on the bug. TL;DR: compile with snapshot, and in Release
mode.

 I'm posting here to see if anyone has experienced this recently.

 We upgraded our scripting environment from *5.1.281.65 *to *5.7.492.44*.
 Everything as far as building with GN has gone
 smoothly, however one odd issue is with the timing of the isolate
 creation:


 _isolate = Isolate::New(createParams);


 This used to be nearly instantaneous (few ms at most), now it's taking
 about 5 seconds on my Windows 10 64-bit
 environment (with a 32-bit build).  The allocator in the createParams
 is using the default v8 allocator.  Will using an
 empty snapshop help?  If we have 20 scripts loaded, that's 100 seconds
 of startup time... way too much.  Any help
 would be appreciated.  Thanks!

Let me know if there are any other tests or information I can provide.

Hey

That sounds odd. Could you file a bug at crbug.com/v8/new and provide the
gn args you used for building?

Thanks
Jochen

I should also note that I can replicate this by simply running the d8 
executable, which seems to take about 5 seconds to bootstrap.
