Bench configuration (dcompact)
Write-side db_bench CPU quota: 50%
(from runner_env.txt cpu_quota_write).
Topling compact: dcompact_worker —
dcompact_worker runs outside the write cgroup and uses remaining CPU cores.
RocksDB compact: compaction_service_spool —
CompactionService spool + out-of-cgroup broker/worker on remaining cores.
Runner hardware/software
| OS | Ubuntu 24.04.4 LTS |
| Kernel | 6.17.0-1022-azure |
| CPU | AMD EPYC 7763 64-Core Processor |
| Logical CPUs | 4 |
| Memory | 15.6GiB |
| /dev/shm | 7.8GiB |
| RocksDB block cache | 7.8GiB |
On-disk DB size (3.7GiB) ≤ block cache (7.8GiB) — cache can hold the entire dataset. So this benchmark mainly shows CPU and memory cost.
