Elixir: first look

I don't have a clear impression about Elixir language yet. I don't like it has Ruby like syntax, but do like it has pipe operator and macros. So, Fibonacci:

defmodule Fib do
def fib(0), do: 0
def fib(1), do: 1
def fib(n), do: fib(n-1) + fib(n-2)
end
defmodule Test do
def tc(f), do: :timer.tc(f) |> elem(0) |> Kernel./1_000
def run(n), do:
tc (fn ->
for x <- 0..n, do:
IO.puts "Fib(#{x}) = #{Fib.fib(x)}"
end)
end

It executes in about 13 seconds which is on pair (even faster for unknown reason) with Erlang, no surprises here.

Out of interest wheres the code for the other implementations?

They are in older posts. The implementations are the same as this Elixir one, nothing interesting, no optimizations of any sort.

Regular expressions: Rust vs F# vs Scala

Image
Let's implement the following task: read first 10M lines from a text file of the following format: then find all lines containing Microsoft namespace in them, and format the type names the usual way, like "Microsoft.Win32.IAssemblyEnum". First, F#: Now Rust: After several launches the file was cached by the OS and both implementations became non IO-bound. F# one took 29 seconds and 31MB of RAM at peak; Rust - 11 seconds and 18MB. The Rust code is as twice as long as F# one, but it's handling all possible errors explicitly - no surprises at runtime at all. The F# code may throw some exceptions (who knows what kind of them? Nobody). It's possible to wrap all calls to .NET framework with `Choice.attempt (fun _ -> ...)`, then define custom Error types for regex related code, for IO one and a top-level one, and the code'd be even longer then Rust's, hard to read and it would still give no guarantee that we catch all possible exceptions.

Hash maps: Rust, F#, D, Go, Scala

Image
Let's compare performance of hashmap implementation in Rust, .NET, D (LDC) and Go. Rust: F#: As you can see, Rust is slower at about 17% on insersions and at about 21% on lookups. Update As @GolDDranks suggested on Twitter , since Rust 1.7 it's possible to use custom hashers in HashMap. Let's try it: Yes, it's significantly faster: additions is only 5% slower than .NET implementation, and lookups are 32% *faster*! Great. Update: D added LDC x64 on windows It's very slow at insertions and quite fast on lookups. Update: Go added Update: Scala added Compared to Scala all the other languages looks equally fast :) What's worse, Scala loaded all four CPU cores at almost 100% during the test, while others used roughly single core. My guess is that JVM allocated so many objects (each Int is an object, BTW), that 3/4 of CPU time was spend for garbage collecting. However, I'm a Scala/JVM noob, so I just could write the whole b...

Haskell: performance

It turned out that it's not Haskell who was slow in my previous Fibonacci test. It was my lack of Haskell knowledge. Haskell has two integral types - Int, which has bounds -2147483648..2147483647 and Integer, which is unbounded. Both types implement Integral type class, so out fib function can be defined in terms of this type class: OK, now we can test performance of the function parametrizing it with the two concrete types. Integer first: We get our previous result ~15 seconds which is rather slow. Now test it with Int type: Whoa! The Int type is ~6 times faster than Integer! And with result of 2.8 seconds Haskell's took the third position in our small rating :) Current list (in seconds): C# - 1.26 F# - 1.38 Nemerle - 1.45 Haskell - 2.8 Clojure - 9 Erlang - 17 Ruby - 60 Python - 120
