Cache hit rate depends on access pattern + replacement policy.

What you're seeing

LRU: evict the least-recently-used. Good for temporal locality.

TTL: evict by age regardless of access. Good for time-bounded data.

LFU: evict the least-frequently-used. Good for heavy-tail popularity.

★ KEY TAKEAWAY
