Earlier the options for profiling Atari binaries performance sucked,
now with Hatari profiler, they don't.
What Hatari provides is as good as what you have available on Linux
for profiling:
- non-intrusive, no instrumentation needed
(symbols can also be provided separately)
- accurate instruction and cycles level information
(both for CPU & DSP + instruction cache misses for CPU)
- memory disassembly with profile information
- top instruction/cycles using instruction and function lists
- callgraphs
- GUI for viewing the data with callgrind data export
(viewing can be done in KDE Kcachegrind)
- tracing for all TOS OS calls and many other things
