If your virtualization platform is AVE, confirm the following configuration items based on the actual software parameters and perform the operations as needed.
Disabling Spectre and Meltdown patches: This operation is optional. Patches are provided for Intel Spectre (CVE-2017-5753, CVE-2017-5715) and Meltdown (CVE-2017-5754), but they may cause a decrease in I/O performance by approximately 20% to 30%. Consider your actual situation and disable the patches if needed.
Switching the port bonding mode: When the cluster's storage network has RDMA enabled and the VDS is configured with Linux Bond, after upgrading the cluster to this version, you can switch the storage network's port bonding mode to balance-tcp under OVS Bond to improve system performance.
