Breaking the Cycle - A Short Overview of Memory-Access Sampling Differences on Modern x86 CPUs
Roland Kühn, Jan Mühlig, Jens Teubner · 2025
As hardware complexity increases, profiling becomes essential for understanding system behavior.This paper compares different x86 sampling implementations for memory access profiling, revealing their complementary capabilities and limitations.Plus, we demonstrate that current abstractions like the perf subsystem inadequately expose platform-specific features.
