I've recently set up Observium to monitor my servers but it's kinda slow. The graphs get loaded one-by-one and slowly appear on the pages.
It's running on a 128/256mb BuyVM with apache2, php5.4 + APC and mysql. The server also runs Smokeping with the RAM usage right now being ~140mb.
Are there any good ways to optimize the setup and let Observium load faster? I know rrdcached is supposed to help but i can't get it to work (and it takes up lots of RAM)
