my network @home @work is fast enough with the defaults in rhl / fc

where would
this be set to?  rc.local?


why not.

a sys file somewhere?

Below is what the contents of the file are...

ifconfig eth0 mtu 1500

# ifconfig | grep MTU

irc this is the default.

iirc you can set it in /etc/sysconfig/network or /etc/sysconfig/network-scripts/ifcfg-*

see  /usr/share/doc/initscripts/sysconfig.txt
# grep -i mtu /usr/share/doc/initscripts-*/sysconfig.txt
   MTU=
     Default MTU for this device
   IPV6_MTU=<MTU of link> (optional)
     Optional, dedicated MTU of this link
       IPV6_MTU="1280"
   IPV6TO4_MTU=<MTU for IPv6> (optional)
     Controls IPv6 MTU for the 6to4 tunnel
       IPV6TO4_MTU="1280"
     Default: MTU of master device - 20
   IPV6_MTU=<MTU of tunnel> (optional)
     Optional, dedicated MTU of this tunnel
       IPV6_MTU="1280"
