Gems Comparison

Code Size

While the Code Size is not a critical topic, it gives you a good idea about how elegant and effective each gem is while accomplishing the exact same task... and the differences are very noticeable.

Less code to perform the same task usually means less complexity and more efficiency, and understanding 10 lines of code is obviously easier than understanding 100 lines, so in the end the Code Size is also a good factor to evaluate a gem.

To be fair with all gems, we removed the generator-related files from Kaminari, and added the lines of ERB templates it uses. We also added the pagy bootstrap extra, needed to render the same bootstrap pagination of the other gems.

Code Structure

Modules and Methods give you a good idea about how complicated is the code. Pagy is not only very simple in structure and number of methods, but 100% of its modules and methods are public API, directly accessible and directly overridable (without monkey patching or subclassing) so there is zero waste there.

The other two gems, conversely, use most of their modules and methods internally, and you would have to deal with a quite complicated "entropy" if you needed some significant overriding.

Moreover, a complicated structure is also affecting speed and object and memory allocation, as the following Memory Profile and Benchmark expose.

To be fair with all gems, we added the pagy_bootstrap_nav_js method needed to render the same bootstrap pagination as the other gems.

Memory Profile

The bar charts show the dramatic difference in object created and memory usage by each gem. So many thousand of objects needed to perform such a simple task, show that there is a lot of expensive waste in how that gems work: this is a mayor performance issue.

This chart shows the memory usage with increasing number of pages shown, starting from a pagination bar of just 2 pages, up to 20 pages. From 2 to 20 pages Pagy has no increase (its chart-line is totally flat on the very bottom part of the memory usage), Will Paginate has a 2x increase (noticeable slope) and Kaminari has a 4x increase (a very steep memory increase)!

You can take a look at the full Memory Profile for each gem in the Details below. Please, keep in mind that each pagination gem may use its own code or may use other gems (rails, activerecord, activesupport, etc.) to do its job. Because of that, we measure the memory allocated by the app as a whole (all gems included), not by the single pagination gem (which obviously wouldn't make any sense).

You can see the the specs broken down by gem, classes, files and location in the memory profile below. Certain rails gem use more memory when used with a pagination gem than when they are used with another one.

Speed Benchmark

This is probably the most important and certainly the most striking comparison, but the result is not completely unexpected. Indeed, the poor performance of Will Paginate and Kaminari is also a consequence of the waste of objects shown in the previous chart. Besides - being small and easy to manage - Pagy has been optimized for performance almost line by line.

Correlation Between Metrics

In this chart you can visually appreciate the difference between the gems by just looking how close or far they are, big or small, fast or slow... You can also hover on the bubbles to read the data for each gem.

The speed is represented on the horizontal axis: left means slow, right means fast.
The size of the code is represented on the vertical axis: bottom means few LOC, top means many LOC.
The size of the bubble represents the memory used: small is good, big is bad
The darkness of the bubble represents the complexity: light-blue is simple, dark is complex.

Pagy is the smallest and lightest blue bubble. Its position is on the lowest and fastest bottom-right area of the chart. The other gems look quite close together on the slowest top-left area of the chart, and very far from Pagy. The dimension and colors of Will Paginate and Kaminari are quite similar between them, much darker and bigger than Pagy.

Efficiency Ratio (IPS/Kb)

Gem	IPS/Kb	Score
Pagy	254.14	~1410x more efficient
Will Paginate	0.83	~310x less efficient
Kaminari	0.18	~1410x less efficient

The IPS/Kb ratio is calculated out of speed (IPS) and Memory (Kb): it shows how well each gem uses any Kb of memory it allocates/consumes.

It is similar to the mileage of a car: how many Miles (or Kilometers) the car is capable to run per each Gallon (or Liter) of gasoline it consumes. It is the ratio between the good thing (distance) and the bad thing (gasoline or money paid for it). The higher the index, the better for your pockets.

For a software the good thing is the speed: how fast it can give you the output, and the bad thing is the memory required to do the job. Below is the calculation for this page: the difference between the gems is so extreme that cannot even be compared in a chart.

The IPS/Kb ratio is proportional to the hardware speed, so you may get different numbers on different hardwares, but about the same score (i.e. the ratios between gems).

For example, if you run this page on a computer that is 2 times faster, you should get all IPS/Kb 2 times greater, but the scores should be basically the same.
