I recently purchased a used MacMini3,1 (Late 2009) with a 2.26 Intel Core 2 Duo processor, and 2 GB of memory. The seller shipped it to me with Snow Leopard installed, and it ran smooth and fast. I just upgraded it to Lion and it's very sluggish. Would adding more memory fix this, or possibly upgrading to Mountain Lion make the computer run better? I installed Yosemite and it was unusably slow. I realize the computer is old, but does anyone have a solution?

Best Answer
The 2GB RAM is the biggest bottleneck here, no matter what you use the Mac Mini for. No recent Mac has been shipped with less than 4GB installed. Although memory management has gotten much better from Mountain Lion > Mavericks > Yosemite, you need to increase the RAM to at least 4GB.
Secondarily, you may be able retrofit a SSD to replace the slow internal HD.
I and my staff upgraded >200 Mac Minis of this vintage from 2GB to 4GB a number of years ago, in anticipation of upgrading from Snow Leopard to Lion & then eventually Mountain Lion. It enabled us to push the use of these computers another 2 years or so.
We've purchased all our RAM from DMS for more than a decade. RAM and HD/SSD retrofits can be found at a number of places, most notably Other World Computing.
