Unless you have actual "shielded" catX with a foil wrapping inside,
and/or separation of the 4 pairs individually (cat6e/cat7), don't assume
it's shielded from microwaves and fluorescent ballasts. Higher the cat,
the better/faster modulation they support for data transmissions
(100m/1g/10g/40g). Cat5e is just fine for gig, most cases (good crimp,
sheathing inside the head, good cable with no tears/kinks) so is cat5.
With NFS as Ben said, those options help significantly too. I mount my
nfs volumes with "rsize=32768,wsize=32768,noatime", and noatime on your
disks in general typically helps quite a bit.
Otherwise, you just have to dig into sysctl's and "performance tuning
linux" docs readily available.
