Please clarify. To which network element are you referring in connection with extended lookup times? Is it the collapsed optical backbone switch, or the upstream L3 element, or perhaps both?
I am talking about the matter that the following topology:
server - 5 meter UTP - switch - 20 meter fiber - switch - 20 meter fiber - switch - 5 meter UTP - server
has worse NFS performance than:
server - 25 meter UTP - switch - 25 meter UTP - server
Imagine bringing this into metro with 1-2ms delay instead of 0.1-0.5ms.
This is one of the issues that the server/storage people have to deal with.
