If anyone's curious: I bumped it up to 250 Mbps at 2010-02-10T00:22Z. Since then, I've received 33.9 million packets, an average of 32.6 per second. I don't have detailed traffic statistics, but I have spent a disturbing amount of time staring at iftop, and learned this: Most of the time, it's not really doing very much traffic. Right now it's doing 35-40 Kbps (inbound and outbound combined), which is more or less normal. IIRC, back when the net speed was 100 Mbps, it was usually 20 Kbps. However, on the hour, it can spike to as much as 1.0 Mbps for a second, staying over 100 Kbps for a minute or two. (It makes iftop use a _lot_ of CPU, hehe!) I haven't done the math to figure out how many packets that is, but I did run sysstats during one of the 1.0 Mbps spikes, and it averaged 490 req/s over 13 seconds. :-D -- Matt Nordhoff _______________________________________________ timekeepers mailing list [email protected] https://fortytwo.ch/mailman/cgi-bin/listinfo/timekeepers
