The iBench link off the performance project page doesn't work (I don't recall it ever working) so should either be removed or changed to one that does.
Confirming. The link http://www.veritest.com/benchmarks/i-bench/default.asp does seem to lead nowhere. ap indicated via IRC that the i-bench test suite may not be open publically, so perhaps the best course of action is to indicate this on the performance page.
It's available at <http://www.lionbridge.com/lionbridge/en-US/services/outsourced-testing/benchmark-software.htm>.
