Hello, all! I have an application. When I start it on my local computer, the amount of rss is abou 10 mb, and vsize: ~45mb . I've deployed it to a remote server (64bit), and started it. When I looked at the process.memoryUsage() results, I've seen that the rss is about 13-14 mb, and the vsize: ~615mb! And those results I got when no users was connected to my server (just a single one). Is it normal?

Why do you care about vsize? Virtual memory is free and a lot of programs allocates gigabytes of VIRT memory. The only issue with VIRT is OpenVZ containers where VIRT is limited instead of RSS. This leads to huge memory consumption on OpenVZ containers for many software projects that are working fine on XEN or real servers (apache2, mysql innodb and java machine are among them). I'd suggest avoid OpenVZ and don't worry about vsize of programs.

Can you give any reference about low level interpretation of virtual memory? On 7 янв, 15:50, Mikhail Korobov <kmik...@...> wrote: > Why do you care about vsize?

The http://linux-mm.org/ site can be helpful, it has tons of info about linux memory management including a whole 8MB pdf book 'Understanding the Linux Virtual Memory Manager' by Mel Gorman. Here is a short article about the actual memory footprint: http://linux-mm.org/ActualMemoryFootprint On 8 янв, 00:35, "Oleg Efimov (Sannis)" <efimo...@...> wrote: > Can you give any reference about low level interpretation of virtual > memory? > > On 7 янв, 15:50, Mikhail Korobov <kmik...@...> wrote: > > > > > > > > > Why do you care about vsize?

It should be noted that in linux each thread has its own stack, this stack is allocated in virtual memory and it is usually consuming about 10MB of virtual memory per thread. So any multi-threaded software will consume a lot of virtual memory and it is a pain to have this software run in OpenVZ containers. I believe node.js has an internal thread pool and this can also contribute to virtual memory consumption. But anyway this shouldn't be a problem unless you're using OpenVZ and if you're using OpenVZ you have many problems besides node.js internal thread pool.
