Express is not actually that much slower - I tested it when I wrote a light-weight Express replacement[1] for my own use (which was mainly about reducing the number of dependency packages from 40+ to 2). IIRC the slowest part was the default 404 router. I was testing with only a few routes though - maybe it gets slower with more (IIRC Express architecture is that all routes are run in serial, so those defined last have to go through all the previous routes first). That and I didn’t add any latency to my tests to make it like the real world - that always has an interesting effect on results. :) Maybe I should re-run those tests for fun … [1] https://github.com/borisovg/node-web-framework/blob/master/README.md https://github.com/borisovg/node-web-framework/blob/master/R...
