Any way to speed up the performance?

[SeniorPlayer]

I decide to use gopher-lua in my game server.
But I want to improve the performance. Is there any tricks to do?

What are you using it for? Personally I would recommend using CGo bindings to luajit if you need performance... Otherwise use something else.

I think gopher-lua`s performance is enough. I have been using gopher-lua in my game server.And I think using cgo maybe worse than using gopher-lua

Well, cgo would have more overhead, but it is definitely faster than gopher Lua. I guess this all depends on how fast you need. If you want to use lua for a game server, use luajit. If you want to extend a go-based game server with plugins or hot swapping, use gopher Lua. I would prefer a type safe language with high performance for game server given the requirements of low latency over UDP being pretty common. Lua has the problem of encountering type errors during runtime which can be very annoying.

You are right.It depends on how fast you need.So I put the battle logic in golang,and other logic in lua.
Well,I would like to use luajit,but i dont know whether GC64 is ready for producer.Do you think cgo+lua5.1 can be faster than gopher-lua,maybe this way is better ?

Almost certainly. The overhead may be higher, but generally the performance should be better. Luajit with go would have the best possible performance. My question is, why use Lua here at all? I love the language, but go is very capable... Why do you need anything else?

Well,it is easier to hire a lua progammer than golang progammer or c++ progammer in my city.
And our gd(Game Designer) is so idiot that they change their design every day,so we need a flexible script language to write logic...

True. But here are my two cents. Don't look to hire Go programmers. Hire good programmers who have done work with C, Java, maybe Python etc. Those programmers with have a very easy time joining a Go-based project given the language is so simple. Additionally, While I understand that design goals may change, this is not really a problem meant to be solved by a programming language. Both Go and Lua can be written in a way that makes it easy to refactor, rewrite and repurpose code when your game designer changes everything. Functional programming may be a helpful paradigm here... SCRUM or Waterfall may also be useful. I've used Lua extensively for both a game and parts of its networking systems. Lua and Go both are great languages with different tradeoffs, but I often find that Lua is faster to write, but it is also makes for buggier code given the weak typing and dynamic nature of the language. Additionally, Lua has very few libraries compared to the many thousands of Go libraries in existance (Go has the bigger community). In short, Lua is good at a few things... and maybe fun to write. C/C++ interop, dynamic typing with decent performance (LuaJIT), plugins and embedded use. Go is good for large, complex programs on the backend that require a team of developers to be productive and write useful programs. Go is much more like a Java replacement, with a focus on being easy to learn, and easy to write. I would take advantage of Go's features and just use it for everything you can on the backend, only using Lua or Gopher-Lua where absolutely necessary. While Lua + Go is a cool prospect, it takes alot of work to get stable, productional quality interop between two languages with completely different designs and goals. YMMV
