When I installed redhat 8 and later upgraded to redhat 9, I decided to install everything. I figured it wouldn't hurt since I had the hard drive space to burn. However, I recently checked my memory usage and was surprised to learn it is using 454/512 oh physical memory when all I have open is the system monitor and Mozilla. I looked through the process list and there is nothing in there to explain the high memory usage. Going by the process list I should be using ~150 mb. Does redhat just take up this much RAM?
