BTW, what is your upload speed rated at? I like to test mine at... http://www.speedtest.net/ Post your results if you get a chance. My uplink is 35 mbps, speedtest generally shows something quite close to that. I just tried setting compression off and deduplication to minimal, though I am thinking that might not kick in until the next file (a few gigabytes from now...)

I meant to post a response to this earlier, your on the right track, the key that is posted on crashplan site is to change the deduplication to minimal, you shouldn't have to adjust the compression, but from what I have read the deduplication is the culprit. Once the inital files are copied you can turn the deduplication back up to normal here is one write up - http://www.technazgul.com/2011/01/crashplan-backup-configurationspeed.html

Here is some excerpts from crashplan site:http://support.crashplan.com/doku.php/feature/data_de-duplication

Data De-duplication Options

You can control the degree to which de-duplication is applied to your backup:
Automatic Full de-duplication is used when backing up over an Internet connection. Minimal is used when backing up directly to disk or over LAN.
Full It is 100% effective, but is CPU-intensive. It is a little slower, but saves bandwidth and disk at destination.
Minimal About 90% effective, it uses several methods to identify duplicate data. It is less CPU-intensive and when used to back up locally will
speed up initial backup speed significantly, typically 400% on a single processor system.
