I'd recommend bonnie++ with a test size that is double your system's RAM. Do this test on both nodes. Second, I've found that realtek network cards are very poor quality. As a test, flip DRBD over to use the unbonded Intel NIC as a test. Simplify things. Go back to a bare configuration (default values for everything), get a base-line performance and then tweak one thing at a time, re-testing performance after each change. -- Digimer Papers and Projects: https://alteeve.ca/w/ What if the cure for cancer is trapped in the mind of a person without access to education?
