...05% For operations like read the max ratio goes up to 10% For operations like write, the max ratio is even more than 40% (Detail of the result in attachment) To make improvement, I have following approaches. I would like to hear your feedback to them. 1. add an argument to rfscall() and rfs3call(), pass XID as an parameter pro: little performance overhead con: change all the code that calls rfs3call() and rfscall(), even they are not related to nfs3 client 2. insert XID into some argument of rfscall() and rfs3call() pro: little performance overhead con: change all t...
