Hi there!
I have some simple tests - 2 GET and 1 POST operations.
VU configured as 100 over 30 minutes run time.
Running tests in docker or terminal leads to high memory usage.
On docker I stop it at ~22GB and in terminal ~8GB (and still growing)
Here is my test file
import http from 'k6/http';
import { sleep } from 'k6';
import { check } from 'k6';
import { FormData } from 'https://jslib.k6.io/formdata/0.0.2/index.js';
const EXCEL_FILE_BIN = open('./XXX.xlsm', 'b')
export const options = {
stages: [
{ duration: '5m', target: 100 }, // traffic ramp-up from 1 to 100 users over 5 minutes.
{ duration: '19m', target: 100 }, // stay at 100 users for 30 minutes
{ duration: '5m', target: 0 }, // ramp-down to 0 users
],
};
export function setup() {
const params = {
headers: { "Content-Type": "application/x-www-form-urlencoded" },
}
const body = {
"username": "XXXXXX",
"password": "XXXXXX",
"client_id": "XXXXXX",
"client_secret": "XXXXXX",
"grant_type": "XXXXXX",
}
const response = http.post("XXXXXX", body, params)
return response.json()['XXXXXX']
}
export default function (data) {
const req_params = {
headers: { 'Authorization': `Bearer ${data}` },
}
const req_post_engagement_document_form_data = new FormData();
req_post_engagement_document_form_data.append('XXXXXX', 'XXXXXX');
req_post_engagement_document_form_data.append('XXXXXX', 'XXXXXX');
req_post_engagement_document_form_data.append('XXXXXX', 'XXXXXX');
req_post_engagement_document_form_data.append('XXXXXX', 'XXXXXX');
req_post_engagement_document_form_data.append('XXXXXX', 'XXXXXX');
req_post_engagement_document_form_data.append('XXXXXX', http.file(EXCEL_FILE_BIN, 'XXXXXX'));
const req_post_engagement_document_params = {
headers: {
'Authorization': `Bearer ${data}`,
'Content-Type': 'multipart/form-data; boundary=' + req_post_engagement_document_form_data.boundary
},
}
const req_get_users = {
method: 'GET',
url: 'XXXXXX1',
params: req_params
};
const req_get_work_types = {
method: 'GET',
url: 'XXXXXX2',
params: req_params
};
const req_post_engagement_document = {
method: 'POST',
url: 'XXXXXX3',
params: req_post_engagement_document_params,
body: req_post_engagement_document_form_data.body(),
}
const responses = http.batch([req_get_users, req_get_work_types, req_post_engagement_document]);
check(responses[0], {
'response code was 200': (response) => response.status == 200,
});
check(responses[1], {
'response code was 200': (response) => response.status == 200,
});
check(responses[2], {
'response code was 201': (response) => response.status == 201,
});
}
What can I do to reduce memory usage?
