Rajesh - if you're performing *exactly* the same execution and are simply asking about the variability - that's just sort of the nature of the distributed RPCs. There can sometimes be pretty wide range of response times in RPCs.
Depending on your frameworks, there are ways to execute queries in parallel which may help. Also, your framework may be trying to "help" by automatically using memcache (e.g., NDB does this, though not for query results); if you memcache hit rate is low, then all the memcache overhead is just waste.
