CACPU optimizes the prefill stage, so its benefits are mainly reflected in TTFT, with limited impact on per-token decoding throughput.

VerifiedTTFT is determined by the Prefill phase and is compute-bound, while TPOT corresponds to the Decode phase and is memory-bandwidth-bound.74% similarUnverifiedTTFT (time to first token) consists of two segments: frontend request preprocessing (tokenization, prompt concatenation) and backend prefill computation, and the KV cache only optimizes the latter.73% similarUnverifiedPrefix caching, by reusing KV vector caches for identical context prefixes, can bring 50%–80% computational savings in AI agent scenarios and significantly reduce time-to-first-token (TTFT) latency.70% similarUnverifiedFor caching scenarios that require an expiration mechanism, the cachetools library's TTLCache should be used, with the TTL and maximum capacity explicitly set.69% similarUnverifiedAs a command-line tool, ttok's main use is to quickly count the number of tokens in text within the terminal.67% similar
