Question: What is your favorite tool for load-testing your app or website and why?
"We have used Perfecto Mobile for years. We can create any number of users to do load testing, and the best thing is that it does testing on real devices in a cloud environment rather than using simulator-based testing. Also, it allows us to test mobile apps on 100+ mobile devices of different make and model. We can test the UI/UX and do performance testing. It's also subscription- and cloud-based, which saves money."
"I like to cross-reference multiple tools, which is why I use GTmetrix. It pulls in data from Google's PageSpeed as well as Yahoo's YSlow. In addition, it lets you compare historic crawls, capture a video of the website loading, test from different geo locations on different internet speeds and browsers and prioritize high-value areas -- all for free."
"I use the tool Google offers because they are the search engine we are looking to rank for. If 85 percent of traffic comes from Google, then why not use the product they judge your site by? They give you the speeds as well as errors to fix."
"Pingdom's waterfall report gives an at-a-glance view of which elements on a page are large and slow. Sort the list of all your elements by size to quickly identify large files and consider removing them to improve load times. Then, sort the list by time to spot those slow-loading elements and, again, consider if you can compress the file or eliminate it altogether."
