We only have jumbo frames enabled on router<->router links. The GigE ports facing the aggregation switches runs standard 1500 MTU.
Hence my original question. Packets across the GE will be 1500 unless you are packing them. April 25, 2001 8:10 PM John Fraizer wrote:
Partially because I can. Partially because there seems to be a performance increase when you start stuffing the pipe.
Assuming you are just passing the packets as received from the aggregation switch, this would only happen if your router hardware was better at managing jumbo buffer allocations than 1500B ones. Clearly it will waste large chunks of memory, so do you have measurements to show the actual performance increase? Tony
