注重性能的桌面程序：Ruby还是Go？

Question

I currently don't know either of the two languages. Design of a piece of software is close to complete.

The intriguing:

• Ruby: Enjoyable. Follows thought process. Made for humans.
• Go: Good performance. Fast compile times.

I don't know about Ruby's performance. If it's a lot slower than Go, I'll go with the latter (talking about typical speed here).

I'll learn both eventually, but right now, this will determine which one first.

Update: It's a very basic image-editing program. Technical and especially perceived speed should be high. Startup time is especially important.

Answer 1

I think those languages are the worst you can choose for performance-critical application. I don't know much about Go, but Ruby is similar to Python (even slower) and Python is slow as hell. As i've been reading, Go is much faster than Ruby, but still is like two or three times slower compared to other programming languages... It depends on what are you trying to do, of course, ie. I wouldn't choose any of those for real-time physics or something like that.

Why is go language so slow?

I've been working with python for a couple of years and it's really slow and I'm sure you will hate it and Ruby is very similar to Python and it's slower but as Go is too new I don't really know much about it, I can't tell..
