I was using an Imac yesterday - mid-2007 revision, I think. Anyway, it had a Core 2 Duo E6420, with 2GB DDR2-667 RAM and was running Leopard. This machine was really slow, it took several minutes to boot Firefox and switching between open tabs alternated between being laggy or unresponsive. I've used a similar spec'ed Macbook Pro (C2D 2.4GHz, same amount of RAM) and that was as fast as the wind.
Any guess as to why this particular machine was so slow? Maybe a shit load of processes were running in the background? Perhaps the HDD is in serious need of defragging?
Cheers.

There is no way to simply know given the info. Whose was it? Most likely it needed some simple TLC (spyware scan, disc cleanup and defrag, or to kill several unnecessary processes at startup. Who knows, though. Could be a hardware issue as well...

OSX does on-the-fly defragging (for the most part, there are some types it won't touch, but it works well) so it is unlikely to be that.
I would suggest looking at Activity Monitor.app (ensure the dropdown says 'All Processes' rather than 'My Processes') and Console.app to see what's up.
From what you've described, it sounds like there could well be a process that's pegged one of more of the CPU cores at 100%

Yeah, my info was much more suited to Windows users. I wasn't thinking...:sweat:

Sounds more like a process eating up all the memory.

It might also be worth doing the following maintenance tasks:
* Hold down ' Apple+S ' then press the power button, wait till a back screen with white text appears and then type the following " /sbin/fsck -fy " - this is the mac equivalent of scandisk, it checks file system consistency and interactively repairs the file system.
* When osx has loaded press ' apple+u ' this will bring up the utilities folder, then find and rune disk untility, then click on repair permissions.
