Ken,

No way. Unless you are using a switching hub which will buffer packets
to handle speed transitions (e.g. 100BT to 10BT) then there is no packet
caching or buffering. A switching hub will buffer the packet long enough
to determine the destination mac address for routing purposes. Besides,
caching in a hub would not increase the speed. This is not like disk
caching which reads ahead in anticipated of more reads.
