Re: [v8-users] Are functions which defined using eval or new Function() optimized?

2018-03-02 Thread Jakob Kummerow
Functions created with eval or new Function will get optimized (after a while, just like other functions -- nothing is optimized on first use). That said, modifying prototypes after the fact tends to have a performance impact, because V8 makes optimizations (all over the place) based on the

[v8-users] Performance impact of increasing Error.stackTraceLimit?

2018-03-02 Thread Benjamin Pasero
Hi, I am wondering what the performance impact would be if I would change *Error.stackTraceLimit* [1] to a high value (e.g. 1000?). The default of just 10 stack frames is little when the error bubbles through a long chain of promises for example. This change would be in production code, not

[v8-users] Are functions which defined using eval or new Function() optimized?

2018-03-02 Thread Koray
Forwarding here from Node.js group as this one is more appropriate. Hello, I have a real time application which will require constant updates / bug fixes. So I will be constantly defining new functions on prototypes or constructors. My question is, will there be a difference between functions
