...and continuing my quest to find the cheapest-best, I have a question about "jumbo frame"...

 

1) will any of the above mobos support it?

2) is it important and why?

3) for whatever it does that makes it good, is there need for something like that, on the "other side" of the network to actually work? (my switch, my other computers)

 

thanks

 

 

For jumbo frames to work, every device in the path must support them.  Both NICs and the switch.

 

Jumbo frames are not going to provide much improvement in an unRAID environment on a local Gigabit LAN. 

 

Jumbo frames are most useful in environments, like a WAN, where packet losses are higher, and in very high packet-rate environments where the CPU usage due to decoding packet headers is high enough to cause a bottleneck.  On your home network, you likely experience very few packet losses and it is unlikely you have packet rates high enough to tax the power of your hardware.

Agreed.  Jumbo frames seem to be like "new and improved!", everybody wants it but cannot ever explain the value they are getting.  There are far more important performance improvements we should be seeking, such as better NICs, faster mobo buses, and improvements in the OS/SW itself.

ok people thanks
