Re: [v8-users] Disable GC during the specified time period
Thanks for answering. OK, any ways I might hack on this in an unsupported way?

[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(); enableGc(); Is there an API for that? I'm aware of a possibility to call major GC runs explicitly, but that triggers non-incremental mark-sweep-compact which is heavy and takes a much longer time than incremental one. What I'd like to achieve is just block GC from executing for a while and resume it a bit later. -- -- v8-users mailing list v8-users@googlegroups.com http://groups.google.com/group/v8-users --- You received this message because you are subscribed to the Google Groups "v8-users" group.

[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 Artem Chivchalov написал: > > Hi all, > > I'm using node.js v5 (V8 4.6.85.25).
