Are you using streams? A while back I experimented with matrix multiplication using streams and they can be very slow:

Hey all, At my day job we saw a 60% performance improvement (cpu utilization) between 1.8.0_40 and 1.8.0_121, and I was wondering if anyone else out there has seen anything like that before or if anyone might know what could cause that given that the release notes don’t directly point to anything.
