Network traffic numbers way off on Linux

RE: Network traffic numbers way off on Linux
There seems to be a skew of 1,58GB on 14GB, which is like 10%. That can have several reasons;

- The type of traffic you're sending. If you're sending small packets, the skew will be bigger; the client only counts the data and leaves the headers out.
- pcap can't keep up. It's not getting enough CPU time and basically dropping packets.
- Interface card offloading is making for giant packets which the client can't unpack.

Most likely, you're running into the first..I've seen that a lot with benchmark tests. The WhatPulse client is built for customer desktops with average workloads, which is where it's pretty accurate.
