slow performance

Awesome work !

But a bit slow (just 16 resp/sec)

First of all you testing a dev server that loads react app each time, per request It's toooooo slow, of course. Also you testing a node.js proxy.

To test production performance you need to build app for production and start it like that:

$ NODE_ENV=production make build
...
$ ./bin/app run -c production > /dev/null

and test it with

$ boom -n 1000 -c 64 http://localhost:5000/
1000 / 1000 Booooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo! 100.00 %

Duktape itself slower than v8 about 2-5 times. There is bad news - react apps render is pretty slow an node.js too. It depends of components amount of you app. Mostly this problems solved via front cache proxy inside the server app or outside. It's up to you which tool to use. If you write performant app you have to use cache independently of render engine, django or RoR or React+Duktape and so on.

Due to performance improvement there are new benchmarks - Requests/sec: 432.2885 for OS X 10.10.4 (14E46), 2,7 GHz Intel Core i5, 8 GB 1867 MHz DDR3
