Sun Aug 16, 2015 4:46 pm

I just use Raspberry Pi 2B+ to do some works,and i had Overclocked to medium; well,the CPU is sufficient to do more things,but when i check the Memory usage,the is almost no Memory can be used,i look forward the next version will have 2G RAM :D

there is the Memory usage picture(i just run python script with pypy in one process):

Sounds like you application is a memory hog. Most programmes should run fine in 1GB.

My first computer had 16KB of memory. That worked fine....

I have yet to run anything on the Pi that might require 2GBytes of RAM. Hardly use a few percent of the 1GBytes normally.

Use the "top" command to see how much memory is used by running processes. I bet your Python program hardly shows up.

Hydrogen don't work and I assume it has something to do with the ram. Also I look forward to speeding up sonic pi. And the PDF viewer is real slow. Nothing I can't deal with.
