Wed 31 Oct 2018 01:57:19 PM UTC, original submission:   From max =dot= bruce12 =at= gmail =dot= com Hey guys, I noticed that your matrix multiplication code had bad cache performance due to a misordering of a loop. In a replicated version of my change, I saw about 20% performance gains on my AMD FX CPU. -Max	Patrick Alken <psa>
