Yes, I suspect your heap is being paged out. I don't know though why your app behaves so differently on different machines. I suspect there is something in your/node.js/node packages code that is OS specific and causes larger memory consumption (e.g. it's buffering too much things in the memory because writing stuff to network/disk does not keep up with incomming data etc).
I don't think any GC tweaks will be helpful here. -- Vyacheslav Egorov On Tue, Jul 24, 2012 at 9:52 PM, spollack <[email protected]> wrote: > here is a reading even closer to the peak: > {"rss":542273536,"heapTotal":523510848,"heapUsed":503801408}. lots of heap > usage! > > as another aside: sometimes i get surprising results for rss, where rss is > considerably smaller than heapTotal/heapUsed in the middle of the run, and > then it quickly returns to what i would expect (rss > heapTotal > heapUsed). > For example, this reading from mid-run: > {"rss":345870336,"heapTotal":516328896,"heapUsed":511765976} Why would that > be? is the heap getting swapped out? > > -- > v8-users mailing list > [email protected] > http://groups.google.com/group/v8-users -- v8-users mailing list [email protected] http://groups.google.com/group/v8-users
