Hi David and Alexandre,
Does this only happen with random writes or also sequential writes? If it
happens with sequential writes as well, does it happen with rados bench?

Hi Mark,
I just ran "rados -p data bench 60 write -t 16" and a few dd tests with no problems at all so at the moment it looks like only random IO triggers the slow writes.
Please do let me know if there are any other tests that I can do to help track down the cause.

Thanks David! We've got some people internally taking a look at this.
I'll let you guys know if there is anything else we need!
Thanks,
Mark
