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. In particular, the operation count for the algorithm must be 2/3 n^3 + O(n^2) double precision floating point operations. 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. 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. 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. Reflection-free Run-Time Dependency Injection framework for Go 1.As a yardstick of performance we are using the `best' performance as measured by the LINPACK Benchmark. Simple CLI tool to get the feed URL from Apple Podcasts links, for easier use in podcatchers Yet another way to use c/asm in golang, translate asm to goasm GitHubĪ set of libraries in Go and boilerplate Golang code for building scalable software-as-a-service (SaaS) applications I also used similar command line arguments format and output format. I fully credit the wrk project ( ) for the inspiration and even parts of this text. These benchmark functions should be prefixed by Benchmark followed by the function name, in the same manner, that you would prefix Test for your test functions. A Simple Benchmark Test Within Go, benchmarking tests can be written in conjunction with your standard unit tests. Recent commits have higher weight than older ones. Activity is a relative number indicating how actively a project is being developed. Stars - the number of stars that a project has on GitHub.Growth - month over month growth in stars. I did not need anything but this to create go-wrk. You will need Go version 1.11+ installed on your development machine. The number of mentions indicates the total number of mentions that weve tracked plus the number of user suggested alternatives. The high-level ISCAS-85 benchmarks discussed in this paper are available below. To handle the initial connection burst the server’s listen(2) backlog should be greater than the number of concurrent connections being tested. to logic circuit rarely do they need to go in the reverse direction. The machine running go-wrk must have a sufficient number of ephemeral ports available and closed sockets should be recycled quickly. This runs a benchmark for 5 seconds, using 80 go routines (connections)ġ42470 requests in 4.949028953s, 19.57MB read no-ka Disable KeepAlive - prevents re-use of TCP connections between different HTTP requests (Default false) no-c Disable Compression - Prevents sending the "Accept-Encoding: gzip" header (Default false) key Private key file name (SSL/TLS (Default ) d Duration of test in seconds (Default 10) cert CA certificate file to verify peer against (SSL/TLS) (Default ) ca CA file to verify peer against (SSL/TLS) (Default ) c Number of goroutines to use (concurrent connections) (Default 10) T Socket/request timeout in ms (Default 1000) H header line, joined with ' ' (Default ) The binary will be placed under your $GOPATH/bin directoryĬommand line parameters (./go-wrk -help) Usage: go-wrk The majority of go-wrk is the product of one afternoon, and its quality is comparable to wrk.īuilding go get /tsliwowicz/go-wrk It turns out that it is just as good in terms of throughput! And with a lot less code. It was created mostly to examine go language ( ) performance and verbosity compared to C (the language wrk was written in. It builds on go language go routines and scheduler for behind the scenes async IO and concurrency. Go-wrk is a modern HTTP benchmarking tool capable of generating significant load when run on a single multi-core CPU.
