Goblin Core SET Benchmark

Generated on a quiet dedicated benchmark host at 2026-07-16 19:23:35 UTC.

Summary

Goblin's RESP/TCP SISMEMBER reaches 2.44M operations/s, 1.33x the fastest incumbent; SBE over 2 MiB shared-memory rings per direction reaches 6.73M operations/s. The populated 1,000,000-member set costs 28.65 RSS-delta bytes/member over RESP versus 44.90 for the leanest incumbent.

Method

1,000,000 distinct 16-byte binary-safe members in one set.
Population uses SADD batches of 128; all timed rows use pipeline depth 256.
Goblin runs GOBLIN.OPTIMIZE key 0.97 after population and before memory/operation measurements.
Goblin Core is measured twice: RESP/TCP and typed SBE over 2 MiB request and reply rings. Every incumbent uses RESP/TCP.
Fixed command rows use the median of 3 native C++ client rounds. Compound churn counts one SREM + SADD pair as one logical operation.
The intersection row uses two equally sized sets with 50% overlap and returns only cardinality.
Servers run one at a time on one serving core; Dragonfly uses one proactor and mini-redis-go uses GOMAXPROCS=1.
Unsupported command cells are n/a; error replies are not timed.
RSS is read from the launched PID. mini-redis-go uses ps -o rss=; other engines use /proc/<pid>/status as VmRSS + HugetlbPages. No server-reported RSS field is trusted.
Redis-family servers are exercised as black boxes; their implementation source is not inspected.
