Hello,
I've a few low end vps and I'm ask myself why some cache a bit of my ram and others don't. E.g. one VPS @DotVPS with 64MB ram caches some of the ram when I simply run apt-get update && apt-get upgrade. One of my other from httpzoom (96MB ram) doesn't do that. On linuxatemyram.com I read, that caching is normal and it provides a faster system. Why is that? Does the system cache some extra files in ram for a faster read and write speed? On Webhostingtalk I've read that the node server of OpenVZ caches and that's why I don't see any cached ram. But both server are virtualized with OpenVZ.
I hope you can give me some answers for my questions :) P.S. both servers are running with debian 6.0.7 64 bit minimal.
Thank you in advance!
