Hi Esbenb, I am having the same issue while writing VDB cache (From a regular fileCache and ROP geometry) on an NFS local set up. my file transfer is capping at 4mbs on the network (While I can write 1GB ABCs or BGEO as my network speed is 10GB). although, writing the same VDB on a local SSD, it is quite instantaneous. I was wondering if you found a solution for this issue. Cheers! Fady.
