Guys, unused RAM is wasted RAM. If your RAM inatumika 90%, it's better than ikiwa 10%. Wacheni RAM itumike. Killing processes doesn't really work. Ata kwa simu, more often than not.
RAM was meant to be used, not to be freed up kila time.
Otherwise, for me, Firefox ni poa ya web dev jobs, chromodo (an ultrasecure version of chrome) is good for normal surfing. No phoning back home to google with my usage statistics. IE for banking/cash transactions.
