mtu property
MTU value is set on the VMKernel adapter for the NFS traffic.
By default standard 1500 MTU size is set in MountDatastore API which is good for typical setups. However google VPC networks supports jumbo MTU 8896. We recommend to tune this value based on the NFS traffic performance. Performance can be determined using benchmarking I/O tools like fio (Flexible I/O Tester) utility.
Optional.
Implementation
core.int? mtu;
