Nope, that is not supported. We are continuously working on making gc pauses negligible. On Oct 30, 2015 8:24 AM, "Artem Chivchalov" wrote: > Hi all, > > I'm using node.js v5 (V8 4.6.85.25). I wonder is there any way in native > code to explicitly disable GC runs (at least

[v8-users] Disable GC during the specified time period

Hi all, I'm using node.js v5 (V8 4.6.85.25). I wonder is there any way in native code to explicitly disable GC runs (at least mark-sweep-compact runs) during the specified period of time, while executing some code sensitive to delays? Something like this: disableGc(); runCodeWithoutDelays();

Re: [v8-users] Re: How expensive is C++ function calls from JavaScript?

I tried running demo again with OpenGL command queue, but that didn't change runtime performance a lot. This time without typed arrays. In profiler, the same function for binding vertex buffer still shows up as a function that taking long time to excute, even though that JS function does not

Re: [v8-users] Re: Function names in CpuProfileNode.

Is there anyway to use something like CreateDataProperty to override the accessor so that the actual function is associated with the property, albeit lazily created? I tried to use CreateDataProperty in place of ForceSet, since ForceSet is deprecated, but that didn't do it, and my property

Re: [v8-users] Disable GC during the specified time period

Speaking of Really Bad Ideas: V8 flags aren't designed to be toggled arbitrarily at runtime. I wouldn't be surprised if lots of stuff started breaking when you mess with flags. (If I were to design an embedder, I wouldn't even provide a "v8.setFlagsFromString()" interface, because having one just

[v8-users] Re: Disable GC during the specified time period

Thanks for the --never-compact flag tip. What bad things can I expect using this at run-time? Also, is the compaction step the most expensive operation of mark-sweep-compact algorithm? And how expensive is the flag switching itself? пятница, 30 октября 2015 г., 10:24:25 UTC+3 пользователь

Re: [v8-users] Object.ForceSet to bypass accessors.

If it was only a performance concern to always go through accessors, it is now also a functionality issue for profiling. The function name in cpu profile result shows up as "get " for the last property this accessor function is associated to. I tried CreateDataProperty in place of ForceSet,
