Note to self #3

Task:

• Measure network throughput of <your favorite dipshit 3rd party app>
• Report traffic over granularity periods
• C99, _GNU_SOURCE

Actions taken:

• Using libpcap in main thread to capture packets (also filtering, etc)
• Piping info into another thread (simple pthread usage) that does the math

Problem encountered:

1. When emitting all the info I read from the pipe to stdout, the average packet count is 2700..3000 packet/s
2. When only the per GP statistics, the packet capture drops to 3-11 packet/s

Extensive head scratching intensifies.

[few days had passed]

Turned out, if I print all the info, of course it captures more tcp traffic, as I'm over an SSH connection! I'm generating that traffic!!!111one

Don't do Java, kids. It's bad for your brains.
