Avoid snprintf+open on each /proc/<pid>/fd entry; keep one O_DIRECTORY handle for readdir and openat during the per-second pagecache scan.
Apply at runtime via graft_bench_yaml so rockside yaml stays at 2; verify base and dictzip10-out copies include the grafted multiplier.
Apply at runtime via graft_bench_yaml; verify base and dictzip10-out copies.
After level0 slowdown and multiplier tweaks, revert base SST size to match rockside defaults and reduce /dev/shm pressure from excess L0 files.
Replace dispatch level_writers with simple through L2, light_zip for L3-L5, and zip at L6 to reduce L0 pressure while keeping deeper levels compressed.
Note that cached reads avoid disk I/O and let the DB benefit in its own way.
