Is Erlang faster than Java?
Now the benchmark says Java took 1.4 seconds and erlang /w HiPE took 11. Running the (Single threaded) Erlang code took me 0.15 seconds, and if you discount the time it took to start the vm, the actual workload took only 3000 microseconds (0.003 seconds).
Why did small talk fail?
Smalltalk failed because it didn’t have portability and low price. There was a easy-to-use and inexpensive implementations of Smalltalk in the 80s called Digitalk Smalltalk/V. There were versions of Smalltalk/V for DOS, Windows and Mac.
Is Erlang the best language?
Overall, Erlang is well-suited for creating fast and scalable web apps. If you get there, it is quite rewarding. There are some caveats, though. All in all, if you do decide to build web apps, using Elixir, a language built on top of Erlang, might be a better choice.
What’s the difference between Java and Erlang concurrency?
In fact, we’ve previously looked at them in a previous post on Flavors of Concurrency in Java. Erlang’s take on concurrency is far simpler, since the immutability of data is strongly encouraged by the language itself, meaning Erlang doesn’t allow its threads to access shared data.
Why is Erlang so bad at math?
Now benchmark aside, the erlang VM essentially just executes machine code at the end, as well as the Java VM. So there is no way a math operation would take longer in Erlang than in Java. What Erlang is bad at is data that needs to mutate often.
What is Erlang used for?
Quoting the language authors: “Erlang is a programming language used to build massively scalable soft real-time systems with requirements on high availability”. Since its inception it has had a solid understanding of the problems it has intended to solve. Any design trade-offs could have been solved by focusing on a single goal.
Why is Erlang so much faster than Java?
The fact that erlang has to allocate memory for every value whereas in java you will typically reuse variables if you want it to be fast, means it will always be faster for ‘tight loop’ bench marks. It would be interesting to benchmark a java version using the -client flag and boxed primitives and compare that to erlang.
