jumbo frames
Authored by: cynikal on Jun 27, '06 05:27:16PM

jumbo frames if you were curious, let you send larger amount of data before having to break that stream of data up because the underlying media can only send frames of a certain size.. normally ethernet has a maximum frame size of 1500 bytes, jumbo frames let you get frames up to 9000 bytes in size, thereby decreasing the overhead of having to re-pack the next amount of data in a new packet (inserting into new headers at one end, decoding those headers at the other end). When it comes to higher speed networks, such as gigabit ethernet, this might help squeeze some more performance out. Of course the switch you're connecting to has to support gigabit and jumbo frames (and in theory, it's uplink should also do the same and so on and so forth).

What i'm curious about is, what kinda performance improvement has anyone seen using jumbo frames?
