Performance<br />
Donald Knuth: “Premature optimization is the root of all<br />
evil”<br />
– especially when based on guesses<br />
– Need clear requirements based on analysis<br />
The performance will heavily depend on the underlying<br />
network path<br />
Tuning performance of existing protocols is possible, e.g.<br />
– For example: TCP can be tuned to not wait for additional data<br />
after a socket writes by turning off Nagle<br />
– However, there is no reliable correlation between application<br />
writes and segment boundaries in TCP<br />
