There's DCPI for Alpha/Tru64 that collects
low-level performance info (for the entire
system incuding the OS and shared libraries)
and also provides tools for correlating all
this info with application code. So you
can quickly zoom into the function in an app which
is causing a bunch of cache misses and
see source/assembly listings annotated with
info from the hardware counters. Cool stuff.
Folks at Compaq used DCPI for tuning Altavista
and Oracle and other large "real-world" apps.
Intel's VTune does similar stuff but I think it only
does it for a specific app, not the whole system.
Unfortunately, the Alpha platform itself is
kind of dead now ...
