I think that Adrian is right, we need more details: - Machine Type - Physical/Virtual/Cloud - NIC details from ethtool (bond and slaves) - MTU size of NIC (bond and slaves) - Disk type - HDD/SSD/NVMe - LVM layout - VDO (if any ?) - Mount options of the bricks - volume info - output of 'cat /proc/cmdline' - tuned profile - Number of clients and TSP nodes in the cluster - Are you using it in HCI mode (where client and server is the same system) Best Regards, Strahil Nikolov В понеделник, 5 октомври 2020 г., 21:27:28 Гринуич+3, Adrian Quintero <adrianquintero@xxxxxxxxx> написа: Hi, Have you tried tuned profiles? random-io what type of storage are you using, spinning or SSD?
