Profiling Node.js

If case anyone is interested in installing dtrace on Ubuntu:

  sudo apt-get install bison flex zlib1g-dev libelf-dev binutils-dev libdw-dev libdwarf-dev
  wget ftp://crisp.dyndns-server.com/pub/release/website/dtrace/dtrace-20120409.tar.bz2
  tar xvfj dtrace-20120409.tar.bz2
  cd dtrace-20120409
  make all
  sudo make install
  sudo make load

I'm surprised more application developers or 'scalability engineers' don't boot up d/sTrace as their tool of choice. It's probably between d/strace & heap allocations profilers for single most valuable tool in my toolchain in the general case for identifying performance problems.

...on SmartOS.
