If you install Node.js using nvm as a binary package such as using:
nvm install <node_version>
You’ll get a usable Node.js. However, this Node.js isn’t optimized specifically for your CPU architecture. To install Node.js specifically for your CPU architecture, we can make use of -march=native provided by mainstream C/C++ compilers. To do this, use the following command to install Node.js instead:
CFLAGS='-march=native' CXXFLAGS='-march=native' nvm install -s <node_version>
This may not boost performance for the general cases. See Does SIMD Improve the Performance of Node.js?
