We are comparing lua and V8 and would like thoughts on heap requirements?
Our use case is to embed an engine inside a hardware device which can take a script and run it.

We would like to have as minimal footprint and over head on device as our input scripts can be really simple expressions.

V8 trades time for space, as a rule of thumb, so if you are looking to

minimize memory usage, V8 probably isn't for you.
A fresh VM instance consumes about 1-2 MB, depending on the
architecture and compiled-in features, and grows quickly once you move
beyond simple one-liners.
You can have multiple execution contexts per VM but each context still
takes up at least 400-800 kB and they can't run in parallel.
