Seems to be a very exclusive search as it doesn't return any information from ITtoolbox, which is pretty sad because the ITtoolbox community is quite large and authoritative.

There also doesn't appear to be a way to contact the admins without creating an account. Take that as you will.
Multi-Core Processor Dilemma
It seems obvious from the results that their code is causing massive cache faults as the single core processor has a 239% performance increase from using multiple threads. That means that each thread is not filling the L2 cache and the CPU is spending over 50% of it's time per thread on waiting for cache faults to be filled from the MUCH slower system RAM. I would send this to them directly, but they've turned off anonymous comments on the blog. The Core Duo processors have relatively small L2 caches that are shared between the cores. so they are also having cache faults there as well, which slows down all the threads. The dual core processors with big dedicated caches are running very well, but would have even better performance if they figure out how to detect the size of the L2 cache per core and then optimize their in memory matrices to best utilize the L2 cache available for the specific system.
