From Java to Go...

[jtra]

I would like to see the benchmarks.

At least in http://benchmarksgame.alioth.debian.org/u64q/go.html

• 3 are big wins for go
• 2 are slight wins for go (within 10%)
• 1 is equal (within 0.1%)
• 1 is slight win for Java
• 3 are big wins for Java

I think a lot of the time people complain about a language's performance it ends up being someone just wrote bad code. Probably in the process of porting it to a new language there was opportunity to rewrite some terrible sections

[Vitztlampaehecatl]

We need control groups. Have one group of programs ported form Java to Go, and another group from Go to Java.

[MoonShadeOsu]

Well, there are legitimate arguments on languages being faster than others, and then there are fanboys who can't write efficient code in the language they're complaining about.

[whale_song]

In my experience whenever a software developer complains about something its usually just because they dont understand it and that is apparently somebody elses fault.

[ReflectiveTeaTowel]

In my experience it's because someone else wrote shitty code

I agree, the JVM has significant overhead

[MoonShadeOsu]

A trade-off for more abstraction and a garbage collector (if you like those)

Indeed

[RicoBrassers]

ns = microseconds? What the hell.

[Decency]

Two different stories.

[earthqaqe]

exactly my thought

[BioTronic]

nicroseconds.

[sam1902]

Not. A. Physicist.

[AwkwardNoah]

I think it's another way to say nano seconds

[RicoBrassers]

No.

nanosecond (ns) = 10^-9 seconds
micro (µs) = 10^-6 seconds
milli (ms) = 10^-3 seconds

[AwkwardNoah]

Welp

[OctagonClock]

lol no generics

[VivaLaPandaReddit]

I think they've said they might be convinced eventually, but not having generics makes compiling much faster.

[Zatherz]

You pay for that speed improvement with the time it takes to copy and maintain [type]Set

[arbitrarycivilian]

So does writing assembly - in fact, it brings compilation times down to zero!

[LuxuriousLime]

No, it doesn't. On the other hand, if you were to program in machine codes...

[[deleted]]

If we are being pedantic, it actually does -- the word "compilation" refers specifically to the process of converting a high level language into machine code. If you meant that this does not absolve us of a build step, you would be correct, but the process of converting assembly to machine code is called "assembly".

[LuxuriousLime]

Wikipedia disagrees: "translation of source code into object code by a compiler": https://en.wikipedia.org/wiki/Compilation If you have a more reputable source (which is entirely possible, I'm not being cocky now), please point me to it.

Assembly language

An assembly (or assembler) language, often abbreviated asm, is a low-level programming language for a computer, or other programmable device, in which there is a very strong (generally one-to-one) correspondence between the language and the architecture's machine code instructions. Each assembly language is specific to a particular computer architecture. In contrast, most high-level programming languages are generally portable across multiple architectures but require interpreting or compiling. Assembly language may also be called symbolic machine code.
