Hi, Let’s try the simple things: Check if you can use MTU9000 and if it’s possible, set it on the Bond Slaves and the bond devices: ping GLUSTER_PEER -c 10 -M do -s 8972 Then try to follow up the recommendations from https://access.redhat.com/documentation/en-us/red_hat_gluster_storage/3.5/html/administration_guide/chap-configuring_red_hat_storage_for_enhancing_performance
