go-wrk's Introduction

go-wrk 0.1

this is a small http benchmark utility similar to https://github.com/wg/wrk but written in go. it has a couple of features absent from wrk

https support (quite expensive on the client side with disabled keep alives)
http POST support
more statistics
leaner codebase

status

this tool is in early stage development but stable enough to run larger benchmark sets. missing features will be added as needed, pull requests are welcome ;)

building

you need go 1.0+ (1.1 is suggested for performance)

git clone git://github.com/adeven/go-wrk.git
cd go-wrk
go build

usage

basic usage is quite simple:

go-wrk [flags] url

with the flags being

    -H="User-Agent: go-wrk 0.1 bechmark\nContent-Type: text/html;": the http headers sent separated by '\n'
    -c=100: the max numbers of connections used
    -k=true: if keep-alives are disabled
    -i=false: if TLS security checks are disabled
    -m="GET": the http request method
    -n=1000: the total number of calls processed
    -t=1: the numbers of threads used
    -b="" the http request body
    -s="" if specified, it counts how often the searched string s is contained in the responses

for example

go-wrk -c=400 -t=8 -n=100000 http://localhost:8080/index.html

Details about the 'Errors'

Hi, I m trying to use go-wrk to benchmark my Java program. I m getting below stats:

How can I know that does these 85632 errors represent? Connection timeout? Details about this would be very useful. Thanks.

Results do not use the http status code response

On my server, I return the following values :

2014/01/23 09:32:50 200 0 GET /rest/d?sort=a&filter=namedfilter&page=1&per_page=
20
2014/01/23 09:32:50 200 0 GET /rest/d?sort=a&filter=namedfilter&page=1&per_page=
20
2014/01/23 09:32:50 200 0 GET /rest/d?sort=a&filter=namedfilter&page=1&per_page=
20
2014/01/23 09:32:50 304 0 GET /rest/d?sort=a&filter=namedfilter&page=1&per_page=
20
(ie I return a 304 one time on 4)

My results are :
...
==========================RESPONSES==========================
20X Responses: 10000 (100%)
30X Responses: 0 (0%)
40X Responses: 0 (0%)
50X Responses: 0 (0%)
50X Responses: 0 (0%)
Errors: 0 (0%)

There is no 30X responses so I think there is a bug on the results.

support custom headers

how to build in go1.15

I try to build in go1.15, but get an error as follows
go: cannot find main module, but found .git/config in D:\code\go\go-wrk to create a module there, run: go mod init
if try order: go mod init, and get an error as follows
go: cannot determine module path for source directory D:\code\go\go-wrk (outside GOPATH, module path must be specified) Example usage: 'go mod init example.com/m' to initialize a v0 or v1 module 'go mod init example.com/m/v2' to initialize a v2 module Run 'go help mod init' for more information.

wrk has https support

It seems like the README here is incorrect and wrk has HTTPS support. maybe it didn't back when this project was started, but it sure does now.

add -r option, it will read all from http response body

When the response body is a stream, there will be a big difference. For example, download a file.

In order to avoid OOM, we can use ioutil.Discard. For example:

if *readAll {
  n, err = io.Copy(ioutil.Discard, resp.Body)
  respObj.Size = n
  return
}

measure data throughput and total received data

How to Post different body in go-wrk ?

All the examples are based on a certain body or params.
But it would be untruthful if we only using one case to test the system/service performance.

So how to Post vary body in the batch requests test?

for example:

# body
{"key": 1}
{"key": 2}
