Does the goal setting influence writing/reading speeds?
Generally speaking, it does not. The goal setting can influence the reading speed under certain conditions. For example, when a file has goal set to two or more, reading the same file at the same time by more than one client would be faster due to the ability for each client to utilize the load balancing effect of the file existing across more than one data server. But in practice, it is very rare in real world situations where several computers would read the same file at the same moment; therefore, the goal setting has little influence on the reading speeds. Similarly, the writing speed is negligibly influenced by the goal setting.
