Get latency looks to be pretty nominal today, around 200ms: http://code.google.com/status/appengine/detail/datastore/2010/05/26#ae-trust-detail-datastore-get-latency
In my experience 5s fetch times are not impossible for cold entities but exceedingly rare, probably less than 0.01% of all fetch requests. So, not sure why you are seeing 5s. Maybe an issue in your serving code not related to the datastore.
