I've opened http://tracker.ceph.com/issues/9285 to track this.

I've ran into this slow request issue some time ago. The problem is like this:
when running with cache tieing, there are 'slow request' warning messages in
the log file like below.
2014-08-29 10:18:24.669763 7f9b20f1b700 0 log [WRN] : 1 slow requests, 1
