I tested it on the only situation I had where it was even remotely worth |
12 |
the effort to try it: NFS over TCP via an old and overutilized router: |
13 |
No measurable effect. I guess a web or mail server (read: something that |
14 |
is not primarily bandwidth constrained and where latency matters) might |
15 |
benefit more. But then again, how do you measure that reliably? |
16 |
|
17 |
You also have to consider where the client might be. A long distance, |
18 |
high bandwidth connection will benefit from different congestion control |
19 |
mechanisms than a local low bandwidth connection. |
