I have spent 2 months and test more than 100 differents versions of memsets, in order to find the best for the old and new architectures. I could post some graphical results in some architectures, from Intel Core2 to Haswell, and for some AMD CPUs. All is in the attachment. -- You are receiving this mail because: You are on the CC list for the bug. ^ permalink raw reply [flat|nested] 5+ messages in thread
