Using notfred's Virtual Appliance. Project 2665 (1920 points) had been using A2 cores and were very efficient (~3100 PpD). Now it is using A1 cores and only garnering ~1900 PpD.
Is my memory bad? I thought all Linux 2665's were using A2 cores. Have they always been A1 cores?
Project 2665 all use A1 core, there is no A2 2665. You may be confusing with 2668/2669, which is true A2 projects or even the initial 2662 (clone of 2665 but for A2).
