CPU profiling is expensive to the point that it skews performance measurement. I edited the prepend.php to just xhprof_enable(XHPROF_FLAGS_MEMORY); but then I get the error:
Unexpected system behaviour.<br /> <b>Notice</b>: Undefined index: cpu in <b>/Users/moshe.weitzman/reps/xhprof.io/xhprof/classes/data.php</b> on line <b>198</b><br />
Would be nice to support running without CPU profiling.
