I am Ilia Kurakin, Software Engineer in VTune Amplifier team. At present I contribute to Network applications profiling.
We've just published the article "I/O Issues: Remote Socket Accesses", describing common way to identify the remote socket cache access issues in I/O workloads due to system misconfiguration. This article is a part of Intel® VTune™ Amplifier Performance Analysis Cookbook.
If you have any questions, do not hesitate to ask me directly in this thread.
