This excludes the use of a fast matrix multiply algorithm like "Strassen's Method" or algorithms which compute a solution in a precision lower than full precision (64 bit floating point arithmetic) and refine the solution using an iterative approach. go-http-routing-benchmark - Go HTTP request router benchmark and comparison. In particular, the operation count for the algorithm must be 2/3 n^3 + O(n^2) double precision floating point operations. A curated list of awesome Go / Golang frameworks, libraries and software. In an attempt to obtain uniformity across all computers in performance reporting, the algorithm used in solving the system of equations in the benchmark procedure must conform to LU factorization with partial pivoting. These numbers together with the theoretical peak performance Rpeak are the numbers given in the TOP500. It does, however, reflect the performance of a dedicated system for solving a dense system of linear equations. Since the problem is very regular, the performance achieved is quite high, and the performance numbers give a good correction of peak performance.īy measuring the actual performance for different problem sizes n, a user can get not only the maximal achieved performance Rmax for the problem size Nmax but also the problem size N1/2 where half of the performance Rmax is achieved. This performance does not reflect the overall performance of a given system, as no single number ever can.
#GO HTTP BENCHMARK SOFTWARE#
For the TOP500, we used that version of the benchmark that allows the user to scale the size of the problem and to optimize the software in order to achieve the best performance for a given machine. The benchmark used in the LINPACK Benchmark is to solve a dense system of linear equations.
#GO HTTP BENCHMARK HOW TO#
A detailed description and frequently asked questions can be found: Ī parallel implementation of the Linpack benchmark and instructions on how to run it can be found at. The LINPACK Benchmark was introduced by Jack Dongarra. LINPACK was chosen because it is widely used and performance numbers are available for almost all relevant systems. Implementing your own suite of benchmarks.As a yardstick of performance we are using the `best' performance as measured by the LINPACK Benchmark. Hopefully this article gave you some indication as to how you can go about When writing your benchmark suites, it’s worthwhile fleshing out multipleīenchmarks like this just to give you a far more accurate representation.

Let’s imagine that our main_test.go file had 2 other test This -run flag takes in a regex pattern that can filter out the benchmarks we Perhaps it might have something to do with your complex request handling logic, your heavy DB access, your caching layer, etc. In a real application, the way HTTP is served is extremely unlikely to be your concerning bottleneck spot. Your benchmark tests, then you can use the -run flag. This is an interesting benchmark of specifically the way they serve HTTP, but nothing else. If you want to specify that you only want to run Might not be ideal if you have a massive test suite and just want to validate In the above example, we ran our benchmarks in conjunction with our tests.
Obviously, as more benchmarks are added to our suite, or the complexity of ourįunctions increases, you should see these benchmarks taking longer and longer. goos : darwin goarch : amd64 BenchmarkCalculate - 8 2000000000 0.30 ns / op PASS ok _ / Users / elliot / Documents / Projects / tutorials / golang / go - testing - tutorial 0.643 sĪs you can see, it ran our Calculate() function 2,000,000,000 times at a Create a new file called main.go and addĮlliots - MBP : go - testing - tutorial elliot $ go test - bench =. Previous article on testing, and try to write a These benchmark functions should be prefixed by “Benchmark” followedīy the function name, in the same manner, that you would prefix Test for your Within Go, benchmarking tests can be written in conjunction with your standard You will need Go version 1.11+ installed on your development machine.In this tutorial, we are going to look at how we can perform standardīenchmarking tests for very simple functions and then move on to more advancedĮxamples before finally looking at how we can generate cool looking flame “Premature optimization is the root of all evil” - Donald Knuth Note - It’s important to note that performance tweaking should typicallyīe done after the system is up and running. By understanding where these bottlenecks lie, we can more effectivelyĭetermine where to focus our efforts in order to improve the performance of our Program performs and analyze where potential bottlenecks are, is really In times where performance is important, being able to benchmark how your Specifically, we are going to be looking at how you can benchmark your Go-based In this article, we are going to be having a look at benchmarking.
