Hi,
We ran a test with 1500 MTU and 9000MTU on a small ceph test cluster (3mon + 10 hosts with 2 SSD each, one for journal and one for data) and found minimal ~10% perf improvements.
We tested with FIO for 4K, 8K and 64K block sizes, using RBD directly.
Anyone else have any experience with this?
Thanks,
Sameer
