📰Introduction
Setting up the Load Profiles in Ready API is an excellent technique to reduce performance risks because it guarantees that an API can manage a typical load. Businesses can uncover bottlenecks in production environments by simulating traffic to an API during development. These bottlenecks can be infamously difficult to locate without a production load in development environments.
📰About Load Profiles
To determine how Ready API Performance should simulate virtual users, we use load profiles in conjunction with the load type. It enables us to see how well the server handles varying loads.
📰Changing the Selected Load Profile
To alter the load profile, follow these steps:
Select the required load test in the Navigator panel.
Choose a load scenario. On the right, the scenario inspector will emerge.
Choose the load profile users require from the drop-down menu.
📰Available Load Profiles
Setting up the Load Profiles in Ready API is determined by the type of load used in the test - VUs or Rate.
Load profiles for the VUs load type function are as follows:
PROFILE
DESCRIPTION
Fixed
Throughout the entire test run, it simulates the chosen number of virtual users.
Burst
Runs a load test with a rapid rise in load.
Ramp Up
Runs a load test with an increasing load over time.
Ramp Sequence
Runs a load test with a series of load increases and lowers.
Random
Runs a load test with a simulated number of users determined by random value generators.
Variance
Runs a load test with a fake number of users based on mathematical waveforms such as sine or saw waves.
Custom
Executes a load test using a specified load shape.
Load profiles for the Rate load type operate as follows:
PROFILE
DESCRIPTION
Fixed
It simulates the arrival of an endless number of users to the tested server per unit of time.
Burst
Runs a load test with abrupt increases in virtual user arrival speed.
Ramp Up
Runs a load test with increasing load speed over time.
Ramp Sequence
Runs a load test with a series of user arrival speed increases and drops over time.
Random
Executes a load test in which random value generators determine the rate of virtual user arrival.
Variance
Executes a load test in which the rate of virtual user arrival varies according to mathematical waveforms such as sine or saw waves.
Custom
Executes a load test with user-specified rate adjustments.
📚Fixed Profile
During the test run, the Fixed load profile replicates the same number of virtual users (VUs load type) or even the same number of arriving virtual users (Rate load type).
The Fixed profile provides many possibilities depending on the load type.
Refer to the following table for more information:
LOAD TYPE
OPTION
DESCRIPTION
UVs
UVs
The number of users connected to the server.
Wait Time
Waiting time before resuming a virtual user.
Rate
Arriving Users

📚Burst Profile
The Burst profile simulates the Base period's base number of simulated users (VUs load type) or arriving virtual users (Rate load type). Then boosts that amount for the Burst period. Following this, the simulation returns to the Base level.
The Burst profile includes varied settings depending on the load type.
Refer to the following table for more information:
LOAD TYPE

Burst arriving users
During the burst phase, the number of users who created the test per unit of time.

📚Ramp Up Profile
During the load test, the Ramp Up profile linearly raises the number of virtual users (VUs load type) or the number of incoming virtual users (Rate load type). Its primary application is stress testing. For example, you can determine at what load the maximum number of per-second transactions is attained before errors occur.
The Ramp UP profile includes several possibilities depending on the load type.

📚Ramp Sequence Profile
Several times during the load test, the Ramp Sequence profile repeats the steady growth. Also reduction in the number of virtual users (VUs load type) or the number of arriving virtual users (Rate load type). The main goal is to undertake peak server testing with "breathing" periods.
The Ramp Sequence profile provides multiple possibilities depending on the load type.
