I'm using Sabnzbd with Tomato on a Belkin N600 HD Router. It is quite fast, but I noticed the disk usage would go crazy with NTFS-3G and slow things down. I moved now to ext3, and it's much better, but if I try to use the router for other things while it is downloading, things are quite slow.
I'd like to put this process at the lowest priority, and managed to do that for the CPU with nice, but the disk option (ionice) is not available. I tried to install the opware package that is supposed to include it, but looks like it won't install for Tomato.
Is there any way I can install this manually? I found the source code on the ddwrt repository, but not sure if it would work?
