Sorry that I mistaked the MB as KB. I don't fully understand your answer.
*1, "the whole RSS is used by V8"?* I think the RSS(11M) is used by the whole nodejs, and heapTotal(7M) is used by V8. V8 creates certain heaps to store js object, map, code and so on.. And heapUsed(3M) is the size of current used size of heap. The remaining part of heap(7-3=4M) is empty, but reserved by v8. Is that right? *2, The remaining memory(11-7=4M), "Mainly buffers used during I/O. "* Because when I check the memoryUsage, nodejs haven't run any file yet. In my understanding, those part memory is used by c/c++ part of nodejs and libs in /deps, including the v8. (running v8 itself needs memory) what does * "buffers used during I/O." mean?* 3, do you know any methods/tools to know the memory distribution of nodejs? how many is used by linuv, by v8 itself, by openssl ... 在 2015年3月28日星期六 UTC+8上午1:02:26，Luca Morandini写道： > > On 26/03/15 16:34, Zidong Jiang wrote: > > > > I think the heapTotal(7K) is included in the RSS(11K), and heapTotal is > consumed > > by v8. is it right? > > Yes and no, the whole RSS is used by V8, but only heapUsed is currently > used to > hold JavaScript objects.
