It is rather interesting to me to see that V8 has been packing so many micro-optimizations and special techniques over the years that now it has become actually feasible to just start cutting back on the optimizations to have performance gains.
What all this enables is, beside having more sensible defaults, is the ability for developers who use V8 with Electron or NW.js to tweak the default behavior of the engine, catering to their application's needs. That is always good.
- cwp 7y agoThat's not what I took away from this at all. They specifically say that Lite mode started out as a way to reduce memory consumption at the cost of performance. Execution time jumped 120%! Then they figured out how to get the memory improvements without the performance hit. The only place where they actually removed optimizations was in generating stack traces, and that wasn't a gain in performance, it was just considered acceptable for that to get slower.
