Implementation

Benchmark TLB performance with different access patterns.

Requirements:

Measure memory access time vs stride
Show TLB miss at page boundaries
Compare sequential vs random access
Demonstrate TLB capacity
Show large page benefits
Calculate TLB miss rate

Why This Matters

The stride benchmark you build here is exactly how engineers diagnose TLB-bound workloads with Linux perf's dTLB-load-misses counter, and it's why databases like Oracle and PostgreSQL explicitly enable huge pages in production to shrink the page-table footprint of multi-gigabyte buffer pools. A workload that looks purely CPU-bound can actually be TLB-bound, and this 20-40 cycle penalty is often invisible until you measure it exactly this way.
