Pyflame is a high performance profiling tool that generates flame graphs
|
|
for Python. Pyflame uses the Linux ptrace(2) system call to collect
|
|
profiling information. It can take snapshots of the Python call stack
|
|
without explicit instrumentation, meaning you can profile a program
|
|
without modifying its source code.
