I’ve just added a page for FractMark, a simple multi-threaded fractal-based benchmark. Read more about it (and download it) here.
On a side note, some of you may be familiar with a similarly simple i/o benchmark called PostMark. It was written under contract for Network Appliance and is known as an easy, portable, random i/o generator. At this point the sourcode has been pretty much abandoned as far as I can tell, so I’ve picked it up and have begun adding some bugfixes as well as some enhancements. The primary things I’ve done so far are to add an option for synchronous writes in Linux, as well as threaded transactions, which should give people the flexibility to test scenarios where they might have many processes creating random i/o.
If this interests you, I’ll be posting the source code and patches coming soon!
