Comment 16 for bug 343714

I just noticed a similar problem. I just upgraded this computer (2 gb RAM) to Jaunty last night (but I installed Ubuntu, not Kubuntu). Now, after about 6 hours of use my System Monitor shows 38% memory in use by programs and 61% in use as cache. We also have Ubuntu 9.04 on a Netbook with 1.5gb of RAM, and it doesn't seem to have the same problem, although it is not used heavily (mostly just a program or two open at a time). I just ran a test on another computer we have in the house with 2gb RAM and Jaunty recently installed. It also shows the cache memory climbing with each application opened, especially KDE apps, although I only tested it for a while, and did not get it over about 50% combined program RAM and Cache RAM. My computer seems worse, but I'm using the Kontact suite and a number of other KDE programs regularly. This problem did not exist in Ubuntu 8.10. There is definitely something going wrong here, but I can't pinpoint it. I tried killing processes, but couldn't get the cache ram to go down.
