There are a lot of simple techniques that can be used to optimize services in a SOA (e.g. caching).
Since each service follows a request/response format, it becomes easier to see where the majority of a request lifespan spends its time to help eliminate bottle necks. You'd be surprised how low the overall latency for a request can be in large companies like Amazon (< 100ms)
