I don't have a monitor app for the NV+ so can't see what the CPU and memory are doing. Do you know of a suitable add-on for the ARM processor model (NV+ v2)? Alternatively is there anything in the logs that will give a clue on CPU and memory?

Regarding the box, it is a ReadyNAS NV+ v2. It has 256Mb of RAM.

I presume the NV+ v2 is running the same RAIDiator 5.3.x firmware as my Duo v2. This doesn't seem to have a built-in resource monitor that shows CPU usage in real time. You would need to install the 'Enable Root SSH Access' add-on, login to the NAS using SSH, and run the 'top' command.

This is much more likely to be a CPU issue than a memory issue.

Quote:The files I'm testing with are a sample Studio Master file from Linn (actually a 24/88 file) so received already packed. It is 42% compressed.

The other is a file I ripped myself with dBpoweramp. The compression is set to Level 5 (their standard) and the files show as 30% compressed.

I looked on the Linn Records site and I found sample downloads for a 24/192 stereo file and a 24/88 5.1 file. Are you using the 24/88 5.1 file? This might explain the CPU resource issue because transcoding a 5.1 file uses three times as much CPU resource as a stereo file.

If you can post a download link or pointer to the Linn test file you are using, I will try transcoding this file on my Duo v2.
