List, I've installed my CentOS Server running progress 9.1D database system, with only 15 users working every day, this server has 2GB RAM, so, my question is: Why the 2GB of RAM is always used? Even with only one user connected... How can I messuare the real RAM MEM used by my system split in proccess? Is there another tools which I use to compare the results from top. Or vmstat? Regards, Israel
