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

I loaded up wireshark and found some possible problems.<div><br></div><div>I sent an email to the service provider and as it turns out, it helped them pin-down a trouble-maker on their network that was sending out loads of broadcast traffic.</div>

<div><br></div><div>Of the four servers, 3 are dells, one running debian/xen, the other two Ubuntu 8.04, and the fourth one, the one with this prob, is a Super Micro running Ubuntu 8.04 w/ a debian/xen kernel.</div><div><br>
