The reason is that, when the code was written, all files were stored on a local disk. NFS only came into play when the t at h server moved to a different machine. Given that we will move away from NFS again, nobody seems to have invested time to optimize for NFS access.

Yes, that is what we found on the dev server too.

Everything can help, but moving away from a NFS attached disk should be the lowest hanging fruit that would make many of the proposed solutions redundant, I'd gues.
