XPerf is a tool that allows you to take a detailed trace of various system activity like CPU, I/O and more...
Because of it's detail you can see stack trace counts, disk position offset graphs, driver calls and so on...
Is there a XPerf-a-like alternative for Linux and Mac OS X? What are the top-notch performance tools there?
Answer
For linux you can combine many tools. top (or htop), iotop, etc. You could also install BSD accounting and use the sa command.
