The issue details page at Sentry's website was experiencing response times of over a second due to a delay in loading the latest event component after the summary statistics had finished rendering. To solve this problem, Sentry used Performance tooling to gain visibility into the requests and identify that the two components were not being parallelized. By starting to load data from both endpoints higher up in the component tree, Sentry was able to parallelize the requests, reducing the response time of the issue page by about 1 second. This fix allowed Sentry's customers to see a faster page and improved overall performance.
