[Cialug] Troubleshooting high latency/low speed

[Matthew Nuzum]

Hello, I've got a server and accessing it is slow lately (about a week now).
Sometimes just slow, other times intolerably slow.

Ping does not indicate too much prob. Latency is about 70-80ms which is
fine. However SSH, HTTP and even HTTPS over a non-standard port all make it
clear there is a problem. Can you suggest how to troubleshoot this?

2010-07-26 16:35:53 (7.59 KB/s) - `jquery.js' saved [72194/72194]

(NOTE that it took 9.3s to download a .js file)

Also, traceroute shows high latency when I test the server, but my brother
tested from ISU and he also noticed the slow speed and he's on ISU's campus
