The Math

Your Cache Wastes
1.07 Years of Compute
Every Year

At 100 billion lookups per year, ElastiCache makes your servers wait 1.07 calendar years of cumulative latency. Cachee reduces that to 48 minutes. This isn't marketing. It's arithmetic.

The Numbers at Every Scale

ElastiCache: 339,000 ns per lookup (same-AZ). Cachee L0: 28.9 ns per lookup (measured).

Annual Lookups ElastiCache Wait Cachee Wait Time Saved Multiplier
100 million 9.4 hours 2.9 seconds 9.4 hours 11,726x
1 billion 94 hours 29 seconds 94 hours 11,726x
10 billion 39.2 days 4.8 minutes 39 days 11,726x
100 billion 1.07 years 48 minutes 1.07 years 11,726x
1 trillion 10.7 years 8 hours 10.7 years 11,726x

At 100 billion lookups per year, your servers spend more than a full calendar year just waiting on ElastiCache. Every year.

What This Means for Real Companies

Each transaction touches cache 10-20 times. Multiply accordingly.

Methodology

ElastiCache latency (339,000 ns): AWS ElastiCache for Redis, same-AZ deployment, cache.r6g.large node, measured P50 latency including network round-trip via TCP. Source: AWS documentation and independent benchmarks.

Cachee latency (28.9 ns): Cachee L0 hot cache, 100,000 pre-allocated keys, 256-byte values, single-threaded sequential GET, 10 measured iterations after 3 warm-up runs. Apple M4 Max, release build with LTO. Benchmark SHA-256: 77a9d4f0e5696b864779821db8495229b23e762dd1049f994267fadf933e6c7a

Formula: annual_lookups × latency_per_lookup = total_wait_time

Reproduce: cd rust && cargo run --release --example benchmark_suite

Note: This comparison measures cache read latency only. ElastiCache provides network-accessible shared state, persistence, and replication that Cachee's L0 in-process tier does not replace. Cachee is designed as an L1 layer in front of ElastiCache, reducing the number of network round-trips by 60-80%. The time savings shown here represent the hot-path reads that Cachee serves from process memory instead of crossing the network.
