The simplest way is to lower the frequency. Especially don't use adaptive frequency (which is the default). This also lowers overhead quite a bit. Also don't use dwarf unwinding. It is very expensive. There are some other ways. I suspect you would most of what you want by just running a fast compressor (snappy or LZO) at perf record time. That would be likely a useful addition. -Andi -- [email protected] -- Speaking for myself only -- To unsubscribe from this list: send the line "unsubscribe linux-perf-users" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
