Yes it pays off to know what to do before you do it, instead of after. If you
complain about speed, is it a general unfounded complaint or did you compare
ceph with similar solutions? I have really no idea what the standards are for

Yes, during my last adventure of trying to get any reasonable
performance out of ceph, i realized my testing methodology was wrong.

You don't even describe how you test? And why would you expect something like
the write speed,
