Re: [v8-users] Re: Isolate Creation Times
I've commented on the bug. TL;DR: compile with snapshot, and in Release mode.

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.

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 Brendan Batesschrieb am Do., 23.
