I have the same(?) problem as Syd, but I am using Xbian 1.0 beta 1.1 (and not beta 1).

- Xbian has low CPU usage: 25% total, 3.5% for NZBget
- Downloading to USB 2.0 harddisk (self powered)
- Pay Newsserver (10Mbps / 5 threads)
- Clean Xbian install
- Xbian and the download packages up to date
- NZBget 11.0 log, shows no errors
- Transmission is stopped

Result: very slow downloadspeed of 40KB/s with NZBget 11.0

I am a complete linux noob, but with the help of Google, I dit some testing:

1. This command downloads a 500MB file:

Code:

wget --output-document=/dev/null http://speedtest.wdc01.softlayer.com/downloads/test500.zip

Result:
Speeds up to 1.6M/s!

2. Test USB disk read speeds:

Code:

sudo hdparm -Tt /dev/sda1

Result:
Timing cached reads: 224 MB in 2.01 seconds = 111.31 MB/sec
Timing buffered disk reads: 66 MB in 3.06 seconds = 21.54 MB/sec

3. Test USB disk write speeds:

Code:

sudo dd if=/dev/zero of=/dev/sda1 bs=8k count=10k

Result:
83886080 bytes (84 MB) copied, 0.603867 s, 139 MB/s
(remark: do NOT do this, it erases the USB disk.. )

Anyone any ideas??

Thanx!

An update to this. Direct downloading via NZBget on the SD card gives speeds up to 800 KB/s! Still not very fast, but a lot faster than 40KB/s. So write speed to USB disk is very slow..
