[OpenAFS] Re: Server disk operations speed

Back to the list.
Due to confidental content, me and Andrew have been troubleshooting the
slow system off-line for awhile. To be fair, Andrew was the brain and I
was the typist. By using Wireshark mostly, it become evident that the
server was spending lots of time speaking to itself. That is, because the
system is in a DMZ, it has both a private and a public IP. During file
transfers, the private IP sent messages to the public one and vice versa,
both being the very same machine.
Then the system was isolated to use the private IP only, and the speed
wen't up considerably. It may not be the only bottleneck, but a major one
anyway, and need to be dealt with first.
Next, I'll try to figure out how to make the server and DMZ play together
nicely, and sustain the higher speed in WAN, too. If anybody has a clear
vision of how to do that, I'd appreciate it. Anyhow, I will report back
if/when I find the solution.
Thanks again everybody and Andrew in particular for spending so much time
