It monitors hardware counters, so it is more similar to 'perf top' than 'htop'/'top', but it can also monitor multiple counters at once. As a disadvantage it can't show the function-level counters, or assembly annotation that 'perf top' can.

So perhaps you could use 'tiptop' to get a general view of what might be slow, and then drill down using 'perf top'.
