Changeset 9038:5602744c6f5a
---------------------------
sim: Add support for tcmalloc if it's installed and available.
This package is available in Ubuntu, Debian, and Redhat as google-perftools.
With multiple tests on a single machine I've seen a little over 10% performance
gain with tcmalloc.

Testing Done

Ship It!

So how does the CheckLib() function works? Does it try to link against the library being checked for?

I don't know, but it does find it and we use it other places.

So does it really work if I just install the appropriate ubuntu package (contrary to what you were telling me in person the other day)?

it does, by the appropriate ubuntu package isn't tcmalloc-minimal, it's google-perftools. The latter creates a symlink such that it's found by ldconfig, checklib, etc.

Just wanted to add that this also works like a charm on OSX with macports.

You have a pending review.
