Load profile
To figure out the load to be generated on the server when creating a test, a load profile is used. The profile determines how the load will be modified and maintained.
Most tools have their own formats for load profiles. When configuring a test via the UI, you can get the final profile by adding sections in the correct order.
Load profiles
line
Linearly increases the load in a given range over a certain period of time.
For example:
{duration: 180s, type: line, from: 1, to: 10000} # the load increases from 1 to 10000 requests per second over 180 seconds
const
Maintains the specified load for a certain time.
For example:
{duration: 300s, type: const, ops: 10000} # generates 10000 requests per second for 300 seconds
step
Increases the load with the specified increment size from one value to another for a certain time.
For example:
{duration: 30s, type: step, from: 10, to: 100, step: 5} # the load increases from 10 to 100 requests per second in increments of 5 and with a step duration of 30 seconds
once
Sends the specified number of requests once and completes the test. There are no restrictions on the number of requests.
For example:
{type: once, times: 133} # sends 133 requests at the start of this test section and completes the test
unlimited
Note
You can set the unlimited load profile only with the help of a configuration file.
Sends as many requests as the target can accept within the established connections without restrictions during the specified time.
For example:
{type: unlimited, duration: 30s} # unlimited load for 30 seconds
line
Linearly increases the load in a given range over a certain period of time.
For example:
line(1, 10000, 180) # the load increases from 1 to 10000 requests per second over 180 seconds
const
Maintains the specified load for a certain time.
For example:
const(10000, 300) # generates 10000 requests per second for 300 seconds
step
Increases the load with the specified increment size from one value to another for a certain time.
For example:
step(10, 100, 5, 30) # the load increases from 10 to 100 requests per second in increments of 5 and with a step duration of 30 seconds
