The usage model is similar like Windows readyboost. Eg, user plugs a USB drive, and we use the USB drive to cache clean pages to reduce IO to hard disks. So far I only did some micro benchmark, for example, access files with size excess memory size. The result is positive. Of course we need solid data for more real workloads. I'd like some comments/suggestions before I put more time on it. Thanks, Shaohua -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
