A small delay in load-time might seem like a minor issue, but in reality even a small change in latency – from 2ms (broadband) to 400ms (3G network) – can cause a page load time to go from 1 second to 30 seconds.\n\nCost Savings – There are many parts of the web architecture such as web servers, load balancers, firewalls, Internet service providers, third party applications and local internet service providers. Load testing allows you to pinpoint bottlenecks in different parts of the web architecture so you only upgrade what you need to.","image":"https://gdm-catalog-fmapi-prod.imgix.net/ProductScreenshot/787057b3-9b6b-4ed1-a740-47c1c2d4d163.jpg","url":"https://www.getapp.ca/software/10147/load-impact-load-testing-tool","@id":"https://www.getapp.ca/software/10147/load-impact-load-testing-tool#software","@type":"SoftwareApplication","publisher":{"@id":"https://www.getapp.ca/#organization"},"applicationCategory":"BusinessApplication","aggregateRating":{"@type":"AggregateRating","ratingValue":5.0,"bestRating":5,"ratingCount":3},"offers":{"price":"299","@type":"Offer","priceCurrency":"USD"},"operatingSystem":"Cloud, Apple, Windows"},{"name":"ReadyAPI","description":"LoadUI Pro is a cloud-based performance testing software designed to help businesses of all sizes create and execute load tests for databases, REST or SOAP APIs, and microservice architecture. It allows IT departments to use existing functional tests to conduct performance evaluation and configure settings as per the business requirement.\n\nIt enables DevOps teams to conduct load tests to simulate visitor traffic, split the workload between instance groups, create testing estimates, and evaluate the performance of APIs. Managers can utilize various built-in testing strategies such as fixed, ramp up, variance, burst, ramp sequence, and more to streamline load simulation and performance testing operations. With LoadUI Pro’s parallel load testing functionality, users can create multiple test scenarios, imitate the expected user volume, and simultaneously run tests against a single API.\n\nLoadUI Pro allows organizations to configure various factors including test length and failure conditions before executing the final load tests. Using the server monitoring capability, administrators can track various metrics across web servers including response time and the number of simulated users using real-time graphs.","image":"https://gdm-catalog-fmapi-prod.imgix.net/ProductScreenshot/cfd0af99-1c54-4e89-a845-d0fffea5fbd1.png","url":"https://www.getapp.ca/software/1999283/loadui-pro","@id":"https://www.getapp.ca/software/1999283/loadui-pro#software","@type":"SoftwareApplication","publisher":{"@id":"https://www.getapp.ca/#organization"},"applicationCategory":"BusinessApplication","aggregateRating":{"@type":"AggregateRating","ratingValue":4.6,"bestRating":5,"ratingCount":5},"offers":{"price":"6449","@type":"Offer","priceCurrency":"USD"},"operatingSystem":"Cloud, Apple, Windows"},{"@id":"https://www.getapp.ca/compare/10147/1999283/load-impact-load-testing-tool/vs/loadui-pro#breadcrumblist","@type":"BreadcrumbList","itemListElement":[{"name":"Home","position":1,"item":"/","@type":"ListItem"},{"name":"Load Testing Software","position":2,"item":"/directory/1959/load-testing/software","@type":"ListItem"},{"name":"k6.io vs ReadyAPI","position":3,"item":"https://www.getapp.ca/compare/10147/1999283/load-impact-load-testing-tool/vs/loadui-pro","@type":"ListItem"}]}]}
