1- Would it affect the memory if i just download and upload big files? Not execute them but download and upload them?
2- I think there is a memory leak in usr/bin/php-cgi and based on my research it is pretty common. It uses most of my ram and there are many of them in htop. What would you suggest?
3- One of the biggest memory users is also iscsiuio. What is it and what can i do about it?
