Got to disagree with you there. CephFS (Luminous) performs perfectly in our setup: single MDS with 8 GB memory cache and dirfrag switched off, pure SSD metadata pool, 4 clients randomly accessing 90 million files mostly under 30kb size.
Reading large directories (500k+ dentries) and unlinking thousands files at once is fast as hell.
