Thanks a lot for the information Matej, Our stats seem to agree with yours regarding the bytes ratio, but there is a significant difference in the flows ratio. Taking into account that we're still evaluating the flows' measurements, there is a slight possibility we might be doing something wrong. Unless our users are opening too many (not http) connections.
