Parsing typescript.js (~ 7 MB, 121 K lines) into an AST with Esprima takes 14 s on Duktape, versus 0.5 s on Node.js. Impressive performance by Node.js / V8 indeed. Note however that this still corresponds to around 10 000 lines per second for Duktape.

Also, binary sizes:
-r-xr-xr-x 1 bob staff 28M Mar 6 20:43 /usr/local/bin/node
-rwxr-xr-x 1 bob staff 330K Feb 11 21:56 ../../duktape-2.3.0/duk

Both with no external dependencies to speak of (Duktape is dynamically linked against system libc, node against libc, libc++ and libicu).
