Sentry Profiling is a solution to help users identify performance issues in their applications by pinpointing the lines of code causing bottlenecks. It collects data on execution times and aggregates results for a comprehensive view of application performance across environments. The tool saves hours of manual instrumentation, allowing developers to build performance as a feature from day one. Sentry Profiling complements other Performance features, including Performance Issues, which detects common problems by grouping transaction data. The tool provides code-level visibility, enabling users to see exactly which call stacks occur most frequently during slow spans and find the root cause without adding instrumentation. It also supports UI Frames visualization on iOS and Android, rendering slow and frozen frames inline with profiling data, making it easier to identify performance issues and optimize resource consumption. Sentry Profiling is now available for additional platforms, including PHP, Ruby, and .NET, and has been used by companies like Azos Seguros and SpiffWorkflow to improve application performance and troubleshoot issues quickly.
