Below is an explanation of what each of the command line flags do:
`perf record` Runs a command under a sampling profiler. See `perf-record(1)`
`--compression-level=1` *optional* Compresses the output file using zstd.
`--compression-level=1` *Optional* Compresses the output file using zstd.
`--user-callchains` Do not record the kernel.
`--user-callchains` *Optional* Do not record the kernel.
`-g --call-graph=dwarf,65528` Use dwarf symbols and a maximum stack size of 64k. If this option is omitted, inlined functions might not be visualized correctly.
