This benchmark suite aims to compare the performance of HTTP request routers for Go by implementing the routing structure of some real world APIs. Some of the APIs are slightly adapted, since they can not be implemented 1:1 in some of the routers.
Of course the tested routers can be used for any kind of HTTP request → handler function routing, not only (REST) APIs.

Go is a great language for web applications. Since the default request multiplexer of Go's net/http package is very simple and limited, an accordingly high number of HTTP request routers exist.
Unfortunately, most of the (early) routers use pretty bad routing algorithms. Moreover, many of them are very wasteful with memory allocations, which can become a problem in a language with Garbage Collection like Go, since every (heap) allocation results in more work for the Garbage Collector.
Lately more and more bloated frameworks pop up, outdoing one another in the number of features. This benchmark tries to measure their overhead.
Beware that we are comparing apples to oranges here, we compare feature-rich frameworks to packages with simple routing functionality only. But since we are only interested in decent request routing, I think this is not entirely unfair. The frameworks are configured to do as little additional work as possible.
If you care about performance, this benchmark can maybe help you find the right router, which scales with your application.
Personally, I prefer slim and optimized software, which is why I implemented HttpRouter, which is also tested here. In fact, this benchmark suite started as part of the packages tests, but was then extended to a generic benchmark suite. So keep in mind, that I am not completely unbiased 😌
Benchmark System:
- Intel Core i5 M 580 (4x 2.67GHz)
- 2x 4 GiB DDR3-1066 RAM
- go1.4 linux/amd64
- Arch Linux amd64 (Linux Kernel 3.17.6)
Besides the micro-benchmarks, there are 3 sets of benchmarks where we play around with clones of some real-world APIs, and one benchmark with static routes only, to allow a comparison with http.ServeMux. The following table shows the memory required only for loading the routing structure for the respective API. The best 3 values for each test are bold. I'm pretty sure you can detect a pattern 😉

The first place goes to Pat, followed by HttpRouter and Goji. Now, before everyone starts reading the documentation of Pat, [SPOILER] this low memory consumption comes at the price of relatively bad routing performance. The routing structure of Pat is simple - probably too simple. [/SPOILER].
Moreover main memory is cheap and usually not a scarce resource. As long as the router doesn't require Megabytes of memory, it should be no deal breaker. But it gives us a first hint how efficient or wasteful a router works.
The Static benchmark is not really a clone of a real-world API. It is just a collection of random static paths inspired by the structure of the Go directory. It might not be a realistic URL-structure.
The only intention of this benchmark is to allow a comparison with the default router of Go's net/http package, http.ServeMux, which is limited to static routes and does not support parameters in the route pattern.
In the StaticAll benchmark each of 157 URLs is called once per repetition (op, operation). If you are unfamiliar with the go test -bench tool, the first number is the number of repetitions the go test tool made, to get a test running long enough for measurements. The second column shows the time in nanoseconds that a single repetition takes. The third number is the amount of heap memory allocated in bytes, the last one the average number of allocations made per repetition.
The logs below show, that http.ServeMux has only medium performance, compared to more feature-rich routers. The fastest router only needs 1.8% of the time http.ServeMux needs.
HttpRouter was the first router (I know of) that managed to serve all the static URLs without a single heap allocation. Since the first run of this benchmark more routers followed this trend and were optimized in the same way.

The following benchmarks measure the cost of some very basic operations.
In the first benchmark, only a single route, containing a parameter, is loaded into the routers. Then a request for a URL matching this pattern is made and the router has to call the respective registered handler function. End.

Same as before, but now with multiple parameters, all in the same single route. The intention is to see how the routers scale with the number of parameters. The values of the parameters must be passed to the handler function somehow, which requires allocations. Let's see how clever the routers solve this task with a route containing 5 and 20 parameters:

Now let's see how expensive it is to access a parameter. The handler function reads the value (by the name of the parameter, e.g. with a map lookup; depends on the router) and writes it to our web scale storage (/dev/null).

Enough of the micro benchmark stuff. Let's play a bit with real APIs. In the first set of benchmarks, we use a clone of the structure of Parse's decent medium-sized REST API, consisting of 26 routes.
The tasks are 1.) routing a static URL (no parameters), 2.) routing a URL containing 1 parameter, 3.) same with 2 parameters, 4.) route all of the routes once (like the StaticAll benchmark, but the routes now contain parameters).
Worth noting is, that the requested route might be a good case for some routing algorithms, while it is a bad case for another algorithm. The values might vary slightly depending on the selected route.

First of all, there is no reason to use net/http's default ServeMux, which is very limited and does not have especially good performance. There are enough alternatives coming in every flavor, choose the one you like best.
Secondly, the broad range of functions of some of the frameworks comes at a high price in terms of performance. For example Martini has great flexibility, but very bad performance. Martini has the worst performance of all tested routers in a lot of the benchmarks. Beego seems to have some scalability problems and easily defeats Martini with even worse performance, when the number of parameters or routes is high. I really hope, that the routing of these packages can be optimized. I think the Go-ecosystem needs great feature-rich frameworks like these.
Last but not least, we have to determine the performance champion.
Denco and its predecessor Kocha-urlrouter seem to have great performance, but are not convenient to use as a router for the net/http package. A lot of extra work is necessary to use it as a http.Handler. The README of Denco claims, that the package is not intended as a replacement for http.ServeMux.
Goji looks very decent. It has great performance while also having a great range of features, more than any other router / framework in the top group.
Currently no router can beat the performance of the HttpRouter package, which currently dominates nearly all benchmarks.
In the end, performance can not be the (only) criterion for choosing a router. Play around a bit with some of the routers, and choose the one you like best.
