JMeter vs Locust, tested: at 2,000 users Locust ran 12 threads to JMeter's 2,039, but one Locust process tops out at one CPU core. Scripts, reports and CI.
JMeter logic controllers tested in one plan: If, Throughput, Loop, While and Transaction, with sample counts and an If condition 22x slower in JavaScript.
k6 scenarios explained with real runs: all 6 executors, startTime chaining, per-scenario thresholds, and a rate test that dropped 686 of 1,001 iterations.
hey load testing tutorial: install hey, read its report, send POSTs with tokens, and avoid the exit code 0 that hides failed runs. Tested on hey 0.1.5.
Generate the JMeter HTML report, read each table and graph, and fix the default that hid 10,000 slow samples from p99. Tested on JMeter 5.6.2 with real results.
JMeter thread groups explained: standard, setUp, tearDown and Open Model groups, the five error actions, and an open model run with 1,732 threads at once.
JMeter vs Gatling, tested: the same 2,000-user run took 2,037 threads in JMeter and 65 in Gatling. Scripting, protocols, reports, CI exit codes and scaling.
Performance testing interview questions with answers: test types, metrics, Little's Law, workload models, bottlenecks, and 4 scenarios, with real test numbers.
wrk load testing tutorial: install wrk, read its output, send POSTs with Lua, and avoid the 2-second timeout that hides slow responses. Tested on wrk 4.2.0.
Apache Bench tutorial: install ab, run a test, read every output line, send POSTs and headers, and avoid the -t 50,000 cap. Tested on ab 2.3 with real output.
Vegeta load testing step by step: install, attack at a fixed rate, write targets files, read reports, ramp up and gate CI. Tested on 12.13.0 with real output.
Artillery load testing step by step: install, write a YAML script, set arrival phases, read results, fail CI on a threshold. Tested on 2.0.34, 1,120 requests.
Gatling load testing step by step: set up Maven, write a Java simulation, inject users, read the report, fail the build on assertions. Tested on 3.16.0.
Correlation in JMeter, step by step: find dynamic values, pick the right extractor, reuse tokens and IDs. Tested on JMeter 5.6.3 with and without extractors.
JMeter interview questions with answers checked against the JMeter 5.6.3 manual: thread groups, timers, correlation, CLI mode, distributed runs and 4 scenarios.
JMeter vs LoadRunner compared on licence cost, 180+ protocols vs 10 protocol families, scripting, scaling and OS support, with OpenText's 2026 names and limits.
Locust load testing step by step: install, write a locustfile, run headless, read the stats and shape the load. Tested on Locust 2.47.0 with 1,026 requests.
Load test event-driven systems by injecting events at the producer and measuring at the consumer: end-to-end latency, consumer lag, DLQ rate, duplicates.
Synthetic traffic is software-generated requests: load tests, monitors, canaries. See the uses and the risks to analytics, WAF rules and third parties.
Size a database connection pool from the database's limits, then confirm it with a load test. Defaults and limits from HikariCP, PgBouncer and PostgreSQL docs.
