Not necessarily. The real time just includes the time the SAS Server was working. If the file system where the data results land are in LA and SAS is writing directly to it, then yes. If the file system is in NY, then no. Display is another issue, as that depends on whether you have a client-server environment and some other issue.
Unless you have a really high speed connection to NY, you should be able to do some rough comparisons with a stop watch and a large data set.
