IBM i - Improve NFS performance on 632B device and allow Jumbo Frames
When reading or saving data to/from NFS server on any NFS server performance is slow if we use MOUNT command, but we can use Jumbo Frames to mitigate.
When using STRNETINS or trying to backup to a virtual optical 632B device connected to NFS server the performance is much slower.
On our tests using DD we could write 2GB in 9 to 32 seconds using mount (no jumbo frames on IBM Cloud PowerVS) , but when trying to backup to the same system using our 632B device the write speed was 1GB per minute.
Maybe a new parameter to improve Wsize, Rsize and Jumbo_Frames on "Service Tools Server LAN Adapter" could improve performance.
This improvemente could allow a good backup mechanism using native commands on cloud environments (IBM Power Virtual Server).
