loading $NVM_DIR/nvm.sh is slow

[miguelmota]

Currently have the following snippet in ~/.profile (from REAMDE)

if [ -e $NVM_DIR ]; then
  export NVM_DIR=$(echo $HOME)/.nvm
  [ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh"  # This loads nvm
fi

However, every time I open a new terminal window it takes 2-3 seconds to run which is too slow.

I'm I loading it incorrectly? I'v resorted to the DMG install from node website because it was a nuisance opening a new terminal window and waiting. Is there anything that can be done? Thanks.
