I've got very different answers and suggestions while googling how to optimize cache. I have clients very interested in extreme performance. We use JotCache and saving on disk and it speeds up the website quite a bit of course (than reading from database). I keep cache for 24hours and recache every night.
Its a webshop with around 3000 visitors per day.
I see you now support Memecached, will we gain much speed by saving to memcache? and of course make sure we have enough RAM on VPS.
