Re: does the 512 model increase the GPU performance?

I usually see a fair amount of swap space used. Though it doesn't seem to be hitting it too much.

If you are in a situation where the system is using Swap (usually on a slow SD card) vs you have more memory and it uses RAM. RAM will show better performance.

Re: USB - the Elephant in our Room

Would it be better idea to have a cronjob that pings your router, and if it doesn't get a response it then brings the interface down and then up again. That way, if you are streaming something through the interface, and it happens to be up and working at the time, then it leaves it alone. The probl...

Re: SSH not working

Hi,

Can you power cycle the RPi? and then attempt to ssh to it again. (Make sure the network cable stays connected during the whole process).

(Also during the boot process, do you see any messages about SSH?)

Re: SSH not working

What happens if you boot up off the Linux Live CD (which you did before) and then run:

Code: Select all

ssh pi@<ipaddress of rpi> 
(or whatever IP address it is)

Also try adding -v to get more output form the command. (You can also add more v's to make it even more verbose).

Re: USB - the Elephant in our Room

The "missing_status" code can disable interrupts for over 100ms, which is a huge problem for other drivers. Another solution is to minimise sdcard accesses. E.g. run your rootfs from a USB drive, or NFS. This should help with this sort of packet loss. If you are not using Sound on the pie, how abou...

Re: Adding RAM to Pi

I think the issue is that the GPIO doesn't provide the speed and bandwidth for managing memory. I've wondered about maybe a custom USB Device with Dynamic Memory (i.e. NOT Flash). You could then tell the OS to use the USB memory as swap partition and maybe that would give you acceptably fast perform...

Re: How to skrink image before loading it on SD card?

The Debian Live people use a squashfs filesystem for the root directory. You could like into the debian live and how it mounts the squashfs.

(Though it probably is better, to just get a bigger SD card)
