Ceph RBD latency with QD=1 bs=4k
You might be asking yourself, why talk about QD=1 bs=4k? Well, from the experience of Wido den Hollander, our colleague at 42on, a single thread IO latency is very important for many applications. What we see with benchmarks is that people focus on high amounts of bandwidth and large amounts of IOps. They simply go […]
