SABnzbd Forums

Hello all,

Recently my old leech-box has failed on me, thus I decided to get a new stronger one which is ready for the future.
My old leech-box was a 3GHz AMD Athlon PC, however even a this powerful CPU was struggling with SABnzbd.

While downloading with 40MBps (~4 MB/s) it almost hit 100% cpu usage under linux, debian.

Now I am wondering, is an atom 330 (1.6 GHz, dual core) powerful enough to fit my needs?
It should at least be able to handle a download speed of 40MBps smoothly using SABnzbd, so there is still CPU power left for example to copy files over LAN.

I hope someone here can give me some disclosure on this matter.

Thanks for your time and effort.

PS: I was using SSL on that 3GHz leech-box, not sure how much more power that requires, but I know it requires a little more CPU power.

I have a little atom box sitting on my bookshelf. I'll test later today and report back.

Edit:

Server: Atom 330, 2gb ram, Debian Stable (Lenny) x64, Gigabit Ethernet, Seagate 7200.11 500 gb SATA drive

Unpacked 1 file/folder in 13 seconds

I have Atom 230 box (being a Windows Home Server).
The average download speed is between 5 and 6MByte/sec of the maximum of 10MByte/sec
that my ISP provides (the CPU never hits 100%, so I'm not sure what the bottleneck is).

Unpacking takes about as much time as the downloading,
but this is also due to the fact that WHS is quite slow when accessing its network drives.
par2 repairing is a challenge, but I rarely need that.
