Is there any way to get the call stack of a function when profiling PostgreSQL with perf ?
I configured with --enable-debug, I run a benchmark against the system and I'm able to identify a bottleneck.
40% of the time is spent on an spinlock yet I cannot find out the codepath that gets me there.
Using --call-graph with perf record didn't seem to help.
Any ideas ?
Cheers,
Dimitris
