Hi, I have the 2011 mac mini that came with OSX Lion Server. I disabled all server functionality and I have 8 gigs of RAM. Running Chrome with about 10-15 open tabs plus and one or two applications, free memory goes down to 20 megs and the system runs very very slow. I tried running the 'purge' command. It helps for a while and then free memory goes down again. See the screenshot below. I have compared the INACTIVE memory with regular OSX Lion. In the non-server edition the Inactive memory is usually below 15% of total RAM. With OSX Server, Inactive memory is usually around 28-30%. Again, I tried running 'purge', that helps only a little. I have thought of two solutions to this: 1) Install 16 gigs of RAM. I'm seriously looking into this and I'm reading old other threads on this subject. 2) Reinstall the OS to put just OSX Lion. I'm not sure I can do this without a way of backing up a lot of data. I bought the mac mini with two 500 gigs HDs. My data cannot fit in the secondary 500 GB disk. What do you guys think? Anybody gone from Lion Server to Lion? How was the process? Does installing the OS touch the second hard drive? It shouldn't right? Thanks.
