Why is Ruby so slow?

Why is Ruby so slow?

Why? Because natively, Ruby is not a slow language. From the 1.9 release, the performance of Ruby is on the same level as other dynamic programming languages, such as Python, Perl or PHP, and the problems they face are related to memory management and time needed by GC to free memory.

Is Ruby on Rails really that slow?

It must be said that most of the time, developers claim that Ruby on Rails is slow because of the initially incorrect project architecture, data caching or database optimization. Rails is FAST in terms of the project development speed. That is the main advantage of Ruby on Rails.

Why is Ruby so slow on Windows?

Ruby being mainly developed on Linux, it ends up mechanically optimised for it. The code is regularly tested for Windows and everything works, but the result is still that developer will spend more time optimising for Linux than Windows.

Is Ruby the slowest language?

Ruby is Slow, so More Ruby is Slower Ruby isn’t a fast language. So, if you execute less of it, you’ll have a faster benchmark result. Feature-rich frameworks like Rails have a lot of code, and execute a lot more on each request because they are doing more stuff.

Which is faster Ruby or Java?

Java code execution is faster than Ruby. The reason is that the Java code is converted into machine language, and the Java Virtual machine executes the code faster. Java and Ruby can be used together, and they complement each other. JRuby is an implementation of Ruby programming language over Java Virtual Machine.

How do I speed up Ruby on Rails?

Tips to optimize the performance of a Ruby on Rails app

1. Choose your hosting provider wisely. Web hosts offer important services like server management and backups.
2. Eliminate the N+1 query problem.
3. Use pluck.
4. Use size instead of length.
5. Upgrade Ruby.
6. Caching.
7. Gems and plugins are your friends.
8. Use background processing.

Why is RoR so slow?

The leading cause of Rails app slowness (according to the American Rails Association of people writing this post) is simply because people making Rails apps aren’t doing the hard work of understanding what’s actually happening underneath. “Rails is slow” is a way too often cited complaint.

Is SQL faster than Ruby?

SQL Databases have been optimized to be very fast and efficient in terms of data retrieval and manipulation. In general, using SQL to retrieve and sort data will be much faster than using a similar command in Ruby.

Is Ruby slower than other programming languages?

You could be told that: Ruby is an interpreted language and interpreted languages will tend to be slower than compiled ones Ruby uses garbage collection (though C#, which also uses garbage collection, comes out two orders of magnitude ahead of Ruby, Python, PHP etc. in the more algorithmic, less memory-allocation-intensive benchmarks above)

Is Ruby fast enough for web development?

Rails [Ruby] is for the vast majority of web applications Fast Enough. We got sites doing millions of dynamic page views per day. If you end up being with the Yahoo or Amazon front page, it’s unlikely that an off-the-shelve framework in ANY language will do you much good. You’ll probably have to roll your own.

How fast is Ruby compared to C?

Ruby 1.9 is about as fast as Python and PHP (within a 3x performance factor) when compared to C (which can be up to 300x faster), so the above (with the exception of threading considerations, should your application heavily depend on this aspect) are largely academic.

Is Ruby good for number crunching?

Ruby isn’t suited well for number crunching; but few languages are, so if you have computational-intensive parts in your program in any language, you better rewrite them in C (Java is fast with math due to its primitive types, but it paid dearly for them, they’re clearly #1 in ugliest parts of the language).
