Query structure with Grafana

I had a quick question as to how best to structure queries in Grafana (to be the lightest load on InfluxDB and to return the fastest).

Would it be better to have separate queries for two different metric series (like octets in, then another query for octets out) or should they be combined in the same SELECT statement?

@jasonmkeller Seperating them into two queries will mean less data over the wire for each individual query and should marginally speed up your queries. However, unless your queries are very large this will not result in a noticeable performance impact.
