Conversation
benchmark results from GCP c2-standard-8 (8 vCPU Intel Xeon @ 3.10GHz): - ember achieves ~878k SET/sec, ~789k GET/sec (pipelined) - latency competitive with redis (p99 0.4ms) - critical finding: multi-core scaling is broken (1.0x on 8 cores) adds performance roadmap section documenting: - known scaling issue - investigation areas (connection affinity, channel contention, allocator) - planned fixes
