The largest group of threads is those from the network messenger — in
the current implementation it creates two threads per process the

Dear Ceph Experts,
our Ceph cluster suddenly went into a state of OSDs constantly having
blocked or slow requests, rendering the cluster unusable. This happened
during normal use, there were no updates, etc.

How much performance can be improved if use SSDs to storage journals?
You will see roughly twice the throughput unless you are using btrfs

because the disk head doesn't have to seek back and forth between

I'd like to use Ceph to solve two problems at my company: to be an S3 mock

We currently store immutable binary blobs ranging from a few kB to several
