I wonder if that's the case. We have an NFS server without NVRAM cache (X4500), and it gets huge MB/sec throughput on large-file writes over NFS. But it's painfully slow on the "tar extract lots of small files" test, where many, tiny, synchronous metadata operations are performed. > I did a smiliar test with a 512MB BBU controller and saw no difference with > or without the SSD slog, so I didn't end up using it. > > Does your BBU controller ignore the ZFS flushes? I believe it does (it would be slow otherwise). It's the Sun StorageTek internal SAS RAID HBA.
