recovery transfer rate not correct
When running all OSDs inside a QEMU VM (with real disks attached through virtio-scsi), the gathered recovery statistics rate does not equal the real IO rate (measured on the hypervisor):
recovery: 1.6 GiB/s, 403 objects/s
This reported IO rate does not match the measured IO rates of QEMU (iotop or htop):
qemu disk read: 236.00 MB/s
write: 218.72 MB/s
All the PGs being backfilled due to rebalancing are 8+3 erasure coding.
Any idea where the calculation is wrong and the result ends up being way too much?
