How does the latency of DDR4 DRAM compare to Intel Optane Persistent Memory when used in both App Direct and Memory Modes for In-Memory database access?

This talk is about the latency benchmarks that I performed by adding gettimeofday() calls around critical DB kernel operations.

This talk covers the technology, cache hit ratios, lots of histograms, and lessons learned.
