This causes an increase in CPU utilization, at least according to commonly used tools.Semi-Offtopic: How do you reliably measure your optimizations?

CPU utilization doesn't tell you anything about any of this, since it counts stalled instructions (waiting for TLB misses f.e.) as utilization. Seems like he's talking about a general phenomenon and using TLB misses as just one example.The only realm in which differentiating between 'real' work and cache misses is important is when you are doing very low-level optimisations - because in this case you can actually edit the instruction stream you're sending to the processor and reorganise data structures to fit in the cache better.In which case you hopefully have better measuring tools than just one utilization number.Just as you may find work difficult when overwhelmed, your processor can slow to a crawl if too much is asked of it at once.Normally, you can avoid this situation by staying away from demanding apps.
