I use an iMac 1'.4.11, 2.1GHz, 2.5 RAM. My photos are stored on two external hard drives and that is where I import them from into LR 2.4. I click on a keyword on rhs of library view, when pics come up on bottom pane I click on one to edit and it takes ages from one to the next. I must be doing something wrong, anyone tell me what? It just takes an age to render.

Few points
1. Your processor speed is ok
2. Your 2.5 gig of RAM is probably not enough - dependant of what other software/applications you run at the same time
3. Your external drives are connected via USB, firewire? This matters a great deal.
4. What speed are your HD's, importantly the HD you have the ircat on
I have just discovered what LR is capable of with a new machine. I went from Pent4 3.4ghz, 2RAM, 54''rpm drive, USB external connections to a new laptop and the difference in stark.
