At Oracle's OpenWorld conference, Intel revealed comparative Optane (SSD) performance on two unspecified Oracle application stacks. http://www.theplatform.net/2015/10/28/intel-shows-off-3d-xpoint-memory-performance/.
Re Optane DIMMs:This is a huge performance improvement, Krzanich said. I think all of us, for any kind of I/O operations, that could see a 5X to 8X improvement in speed thats what we have been looking for. It is an improvement in both performance and latency. But there is really more to this technology. Intel Optane SSDs provide about 200X less variability, and that is an additional benefit that you can count on for your datacenter.
Krzanich said that Intel will have working Optane DIMMs ready later this year for early testers, and will combine the performance of DRAM with the capacity and cost of flash. What this means is that a mix of DDR4 and Optane DIMMs in a two-socket server with a total of 6 TB of addressable memory, virtually eliminating paging between memory and storage, taking performance truly to a whole new level. Krzanich added that data encryption in the DIMM, so that data at rest on the DIMM it will take us all a while to get used to that is secured.
