Are you sure it was the NFS that was the problem? Were the files for
your PXE stored on the server using a traditional hard drive or an
SSD? If it was a traditional drive, was that drive also used by
something else (your server's OS drive, or multiple frontends, or
maybe even your mysql database)? It would be really unfair to host
multiple systems on a single HD and then just claim that NFS was the
problem, when I'd suspect a more likely cause there was slower I/O
disk being overworked. Now if it was an SSD in the server that the
files were stored on, then I guess yeah...NFS would be my guess
(assuming you have no network issues otherwise).
