Does anyone know how I can discern correct number. I am defaulted at 1500... I would like to optimize my broadband, could someone set me straight. I use Verizon dsl and am on the west side of LA.
TIA

What is MTU? And where to you change it?

The Maximum Transmission Unit (MTU) is a parameter that determines the largest datagram than can be transmitted by an IP interface (without it needing to be broken down into smaller units). The MTU should be larger than the largest datagram you wish to transmit unfragmented. Note: this only prevents fragmentation locally. Some other link in the path may have a smaller MTU: the datagram will be fragmented at that point. Typical values are 1500 bytes for an ethernet interface, or 576 bytes for a SLIP interface.

You make the change in your router's settings.
