LapanWebsite on "High outgoing traffic"

In last 4 days I have traffic of 2.6GB in my CP.

By google analytics in last 4 days I had:

Visits
370
Unique Visitors
344
Pageviews
966
Pages / Visit
2.61
Avg. Visit Duration
00:01:47

Is this possible?
370 visits, 2 minutes each = 2.60GB of outgoing traffic?
