REST API Performance & Load Testing (Apache JMeter) I will perform comprehensive performance and load testing using Apache JMeter to evaluate the load capacity, stability, and reliability of your REST APIs under real-world conditions. Testing Objective • Validate system performance and load-handling capacity • Identify bottlenecks and failure points under concurrent usage Test Configuration • Concurrent users: Up to 100 users • API coverage: GET, POST, PUT, DELETE requests Key Parameters Checked • Response time (avg, min, max, 90th/95th percentile) • Throughput (requests/transactions per second) • Error rate (4xx/5xx responses) • Concurrent user stability • Latency and server processing delay • Payload handling for POST/PUT requests • CPU and memory impact (if monitoring access is available) Testing Scope • Realistic load simulation with ramp-up and steady state • Response consistency under increasing load • Identification of slow or unstable endpoints • Determination of maximum sustainable load Deliverables • JMeter test plan and executable scripts • Detailed performance report with metrics and graphs • Summary of findings and optimization recommendations • Clear assessment of system load capacity I can start immediately once API documentation and test environment details are shared.

Hi there, This looks focused on validating how your REST APIs behave under load rather than functional testing. Building the JMeter setup from scratch means defining a clean test plan that reflects real usage: configurable thread groups ramping up to ~100 concurrent users, separate samplers for GET, POST, PUT, and DELETE flows, and proper parameterization so requests aren’t replaying static data. To make the results meaningful, the scripts should include realistic think times, clear assertions on response codes and latency, and listeners that capture throughput, error rates, and response time percentiles. Structuring the plan so it’s easy to adjust user counts or reuse against other endpoints will help you extend the tests later without rebuilding everything. Once complete, you’ll have runnable JMeter scripts that clearly show load capacity limits and where bottlenecks start to appear. Best regards

I’d love to help you get these JMeter scripts up and running. ​Since you’re looking to check your system's load capacity at a 100-user threshold, I can build a clean, modular JMeter suite from scratch that covers the full lifecycle of your REST APIs. ​Here is how I’ll handle the project: ​Scripting: I'll build scripts for your GET, POST, PUT, and DELETE requests, ensuring they include proper correlation and parameterization so the data stays dynamic. ​Load Simulation: I’ll set up a thread group specifically tuned to 100 concurrent users to see exactly how your system handles the pressure. ​Capacity Insights: The goal isn't just to run the test, but to find where the "breaking point" is. I’ll provide a clear summary of response times and any errors that pop up during the POST or DELETE cycles. ​I’m comfortable working with REST APIs and can deliver the .jmx files so you can run them whenever you need in the future. ​Looking forward to hearing more about the endpoints you need tested.

NO SATISFACTION, NO PAYMENT I understand you need performance testing focused on load capacity to simulate up to 100 concurrent users making various REST API calls including GET, POST, PUT, and DELETE. Ensuring these tests are accurate is critical, as any errors could lead to wasted budget, stalled growth, and technical debt by failing to identify potential bottlenecks. My approach centers on clear communication, taking full ownership of delivering reliable results that ensure your system performs smoothly under expected user loads. I focus on providing actionable insights that directly support your business goals. I have completed similar projects outside this platform and offer a slightly reduced rate initially as a strategic decision to establish a strong presence here, not because of lack of expertise. There is no pressure to commit immediately; early alignment on goals matters most. Please respond with any questions or a quick clarification so we can ensure full alignment before proceeding. Worst case, you walk away with useful clarity on your project. Warm regards, Liam.

Hi let’s start to know api better for this a small performance testing will be done this will helps us to see if the API is able to handle a few users, an analysis report will be delivered with all the observations and details. Then if the light is green will continue with a regular performance test with 100 users now more activity must be reflected on the api server, response times, cpu, errors in case any bottlenecks issues they will be added in the report and let’s work with dev team to fix and improve if any issues. Finally if the API is able to handle the tests with no issues additional tests can be added just find out a breaking point, anyway let me know if you agree with my plan and want to know more about it.

@cpatino

I've set 5 days just because I don't know how many endpoints do you want to exercise, but for just a few endpoints and without CSFR, it should be 1-2 days. We can meet or at least generate a document of the endpoints to be exercised Identify the dependencies (probably we have to execute, eg, POST before GET, etc.) Verify the behavior with one user Scale to 100 threads/users

I can design and execute a JMeter load test to evaluate your application’s load capacity with up to 100 concurrent users. I will create scripts for your GET, POST, PUT, and DELETE REST APIs, configure proper ramp-up settings, and measure key performance metrics such as response time, throughput, and error rate. After execution, I will provide a clear HTML report with analysis and basic optimization recommendations. I will ensure the test is stable, well-structured, and delivered within your budget. Within your stated budget, I will provide one baseline load test up to 100 users, including script setup and a summary HTML report. Additional scenarios or revisions can be handled as a separate milestone.
