StackExchange.Redis is the baseline. A ratio below 1.00 means Respire completed the operation faster.

Visual comparison

StackExchange.Redis has no built-in server-assisted client cache, so its values are ordinary server reads. Respire server reads are included for a like-for-like uncached comparison.

Client-cache hit time — net10.0StackExchange.Redis and Respire server reads vs Respire client-cache hit. Shorter bars are faster.
