I've been trying to diagnose some latency issues with my internet connection.

I've been lagging out of online video games and such, which of course could be their server's fault. So, I've been running ping some. It doesn't indicate anything unusual, but it does act a bit strange.

I can start it with something like ping internethost -i 0.1 so that it will send a ton of packets, and every 10-20 seconds it will appear to just freeze for 2 or 3 seconds. The packets are still being received in the right order though, and there is no packet loss. The weirdest thing is that after the little freeze up, it will usually just report a ping time that is about 10-30ms higher than the average.

How does this happen? Is ping still being accurate?

I'm using Arch Linux. The host I'm pinging is my website, which shouldn't be doing any kind of ping slowing or filtering.
