Throttling does not affect packet latency. At the router level, it generally involves selectively discarding packets. Data is not drip-fed at the bit level or byte level.

In order to intentionally affect latency, it would have to do a lot more work by buffering them for a period of time before forwarding onwards.

Now throttling can affect latency of logical messages within a TCP stream depending on the size of those messages, due to the retransmissions required, but does not affect the latency of UDP packets as stated.

I'm not sure that net-neutrality would help this. ISPs are blocking high volumes of UDP packets, and they'll claim it's to protect users from DDoS attacks. They may even be telling the truth.

The summary is also badly composed by following the latency complaint with a quote about blocking traffic. That is, unless you consider a blocked packet to have infinite latency. The letter is much more vague about what their actual latency complaint is, other than, you know, latency is bad.

That is until Borderlands came out. This game is a wretched reminder of the 'bad old days'. I spent hours scouring forums and search engines, fiddling with my router, and trying to set it up so that I could host a game for my friend. No dice. Even setting my computer as the DMZ host didn't help. The only way myself and another friend were able to play was through a third friend who didn't have any issues.

For what it's worth, most people are playing Borderlands online now using GameRanger for exactly this reason, because it eliminates all these problems. Gearbox has unofficially recommended it as a solution as well.

If you are a potential fit for a particular test group, we'll send you an invitation email, asking you to run a detailed Performance Test on your network connection and your computer configuration.

So they can counter their critics by saying they had a positive public beta, yet with a carefully controlled group, to ensure pesky real-world situations don't damage their hype for gaining investors.

CLucene is faster, and uses less memory, from what is basically a direct port. The README includes some benchmarks:
