.jsappears with the first use, to disambiguate from other things called "Node", and
Node(without the .js) afterwards. One way to think of this is that
Node.jsis the full name, and
Nodeis the more familiar first name.
node, lower-case to match the binary's name itself.
node core. (See node core vs userland.)
Currently, by default v8 has a memory limit of 512mb on 32-bit systems, and 1gb on 64-bit systems. The limit can be raised by setting
--max_old_space_size to a maximum of ~1024 (~1 GiB) (32-bit) and ~1741 (~1.7GiB) (64-bit), but it is recommended that you split your single process into several workers if you are hitting memory limits.
