Hey!
I'm considering getting a Bubba for my home network, but I'd like to know what transfer speeds I can expect?
I have a few similar boxes laying around here atm, like the Linksys NSLU2 (running Debian) and a few OpenWRT enabled devices. They all suffer from little ram though, and if I'm lucky I can reach speeds up to approx 3.5 megabytes/s over unencrypted FTP (using vsftpd as my daemon).
My NSLU2 runs a ARMv5TE (IXP) based CPU at 266 MHz, which should be similar to your ARM9 cpu, so do you think the extra RAM in Bubba will be able to achieve higher speeds?
Also, what are your plans for the future? I really like the idea with an "open" arch, a device being sold to be easily customized and not branded as some random network/router equipment, with the much needed extra ram. Have you ever considered building a similar device on the new Atmel AVR32 UC3 family? I think circuit size could be greatly reduced with on-chip ethernet and usb controller.

Speeds
Hi Mange,
Regarding FTP speed, you are right that Bubba is in the same range, normal transfer speeds are between 3-6MB/S depending on the direction of the transfer and the size of the file transfer.
Memory size wont affect this to any greater extent. At least not for big transfers, bigger than the ram size. But for smaller ones it do affect transfer rates since it can cache more data.
Regarding AVR32, Bubba is built on AVR32s cousin, AT91, and do already have on chip ethernet and usb controller. So there we unfortunately cant make any savings
