It doesn't seem to make my system run slowly, but it concerns me definately.Linux keeps disk blocks in memory for faster access, in your server there are 158Mb aprox. in buffers. This amount will grow/shrink dinamically depending on the number of processes you're running. When the memory becomes full linux will start to use swap. In your server there is no much swap used, so all seems to be fine to me. HTH
Thanks to both of the people who have responded so far. I am glad to know it is working fine. I never noticed that much use of ram on any of my other systems ( I probably never checked ), so it had me worried :)
