Calculating the avg time between two time stamps

Elastic Stack Elasticsearch
1

Using ES 1.2.2

The below aggregation will give me my average requests per second and the
average response times for each second.
Is this the only way to do it or is there better way? Since scripting is a
bit slow?

"aggs": {
"tps": {
"date_histogram": {
"field": "stampStart",
"interval": "second",
"order": {
"_key": "asc"
}
},
"aggs": {
"avg_resp": {
"avg": {
"script": "doc.stampEnd.value - doc.stampStart.value"
}
}
}
}
}

The best option could be to compute that at index time.
On a client level or by using the new transform feature: http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/mapping-transform.html#mapping-transform

Cool! So for the new feature...

All I need is an empty field called "avgRespTime" and in my mapping define a transform for this field which compute the time difference between thw two stamp times?
