is something wrong with my mini?!?

xbench doesn't do anything really memory intensive, so adding more memory won't necessarily change your xbench scores.

 

i agree with Bear, plus Xbench isnt always the say be all end all when it comes to testing speeds and whatnot

 

How many times in a row did you run x-bench? Do the systems have the same model disk, etc. xbench numbers are only meaningful in a limited way.

Does the machine do what you want it to do? Does it seem fast enough? That's all that matters really.

 

Adding memory isn't something I'd expect to cause a bump in benchmark results since what the added memory does more than anything is reduce the number of 'page outs' that the system has to do. Since page outs are when MacOS shifts memory contents to the hard drive (and then subsequently back again) and since the hard drive is noticably slower than RAM, page outs cause Macs to slow down. Thus, more memory means that in normal use, the system will run quicker and feel far more responsive, but in benchmarks will make no difference unless the benchmark test contains memory dumps to HD and from the HD.
