The optimizations I made were relatively minor, and most of my speed came from leveraging the right Python libraries. Java, Rust & Ruby have built-in support for concurrency, but I haven't used those languages that much. Full access to Erlang functions. I ran the sample data you have in a single “thread” (called a light-weight process in Erlang). Maybe they are bidding on ads, or tagging posts with "likes" and so on. point you had on performance seemed to be based around a single implementation (mochijson) of a JSON library and more generally strings. This can have significant impact in performance and memory use. The problem with scaling languages like python and ruby in my experience is the number of moving parts and jump in deep knowledge required to scale when your application takes off. Elixir is a functional programming language which is mainly designed for maintaining the distributed and scalable applications. Since it handles traffic from all of our customers’ customers, it must manage thousands of requests per second, reliably. I think you’d be VERY pleased with its performance if you had stuck with it. When comparing Python vs Elixir, the Slant community recommends Python for most people. The general consensus in the Go community is that the default http.Handler is sufficient for most things. If the machine is rebooted for some reason, the pending messages will be lost, and will never be processed. Go for what your team feels good with. Increase the rate of innovation in the world. Active 9 years ago. Sure, np. We’re running it over at twistedmatrix.com for our primary DNS and we’ve had no problems. Some subsystem crashes and restarts? We get around this problem by launching one API server per core and load balancing with nginx. Finally, let's look at the classic Quicksort algorithm in both Python and Erlang. Rewriting systems in another language can certainly be accomplished. Obviously I agree with the advice though. I’ve only recently been introduced to Erlang and have been using it over the last year professionally. I will investigate Erlang Clusters. It's not going away any time soon. In all fairness, Elixir/Phoenix could become as well-learned as Ruby on Rails. . (And btw when I say Erlang I also mean Elixir, they both share the same VM so most things apply to both). 3) – Rows: 331 Files for python-erlang, version 0.2.2; Filename, size File type Python version Upload date Hashes; Filename, size python-erlang-0.2.2.macosx-10.5-x86_64.tar.gz (2.8 kB) File type Dumb Binary Python version any Upload date Nov 27, 2016 Hashes View Note that you could then have had memory-only Mnesia table (adding transactions, sharding and distribution on top of ETS) to do it. I'm curious to know how this author thinks differently. (as mentioned), or can still use a database (say Postgres), so it really depends. You handle that with multiple nodes that sync their state. I know it’s super weird when you first get into it, but you’ll definitely grow to love it for problems like this. - It looks like the SQL queries produced by pure_python() and simple_sql() are structurally different, which would make any comparison worthless. Are there any figures available about the performance of the API server while running Erlang? In the language and/or the standard library? Game companies come to mind first and foremost but they're hardly the only ones. . Nope, that’s not the right way. But Erlang is a the secret sauce (so to speak) for a high concurrency fault tolerant backend. Dubious in that he gave an arbitrary and unsubstantiated 500ms benchmark for Python. Python is to get small stuff done quickly language for me. Yes, the asyncio library was introduced in Python 3.4. Erlang certainly faces performance issues, but Python does as well. I read your problem description and was curious how Erlang, written by someone who has some professional experience with it in a performance-oriented world, would do in comparison to the Python results. I don't see how replacing Python with Erlang changes anything in this regard. Ask Question Asked 9 years ago. Most of the time you don’t need to muck with strings too much, just pass ’em around or compare them to something. “Finally, we use a few stateful, global data structures to track incoming requests and funnel them off to the right backend queues. The Computer Language Benchmarks Game Which programming language is fastest? Why and How I Switched from Python to Erlang. So you have to measure. Python and Ruby get you where you need to be fast, and if you get far enough and need to scale, there are a huge number of options, from stalwart holdouts like Java and C# (now on Linux!) Erlang is generally considered exceptionally maintainable due to low number of lines of code, functional idioms and tons of real world reuse. May I ask you some questions? It was quick and easy for me to implement a clear and easy-to-use analog in Python, and I was able to enhance some of the backing algorithms in the process. > Python 2 & 3 also have threading and multiprocessing for concurrency. We get around this problem by launching one API server per core and load balancing with nginx. You are building a large, ... (Python Code) Jack Dong in The Startup. Not sure how deeply you want this explanation to go, so will stop here. Name-dropping Erlang string performance without doing benchmarks is kind of irresponsible. I saw a thread on Elixir a couple of days ago and it piqued my interest and I saw a couple of videos that were posted there, one from some Ruby Conf that claimed that Elixir was giving better results (in request time) than rails.
