About:
rbspy is a sampling profiler for Ruby that measures where your Ruby program is spending its time without requiring code changes. It works by sampling the stack traces of a running Ruby process, providing accurate performance insights with minimal overhead. This makes it ideal for profiling production applications or long-running processes.
|
Key Features:
- Zero code instrumentation required
- Low overhead for production use
- Supports Ruby 2.0 through 3.x
- Generates flame graphs and text reports
- Works with running processes or new commands
|
Use Cases:
- Identifying performance bottlenecks in production Ruby applications
- Profiling long-running processes without significant slowdown
- Analyzing Ruby code performance during development
|
Alternatives:
-
ruby-prof
– Requires code changes and has higher overhead
-
stackprof
– In-process profiler requiring instrumentation
