I recently received my RPI, and I have it booted up with Debian. I have set up SSHD and running LXDE(localy, not via SSH). During installation of additional programs via apt-get, the CPU Usage monitor on the panel shows 100% usage, but HTOP in my ssh session shows less than 10% usage. The installation process takes incredibly long time, even for small programs with few dependencies. What is causing this strange reporting of CPU usage?
