i doubt this is a hard drive seek time issue. i think the word "lag" is not really appropriate. I'm talking about being able to grab the scrollbar and smoothly scroll up and down through your library. I mean, its just text and some small album cover images. If the same data were rendered in HTML in IE it would be just fine. I think iTunes is just shoddy programming.
See that's the thing though, I use mine in Album view (which seems to take the most system resources), and on my newest computer, it's smooth. But on my two eMachines, it's jitters and jerks around like crazy. Grabbing the scrolbar and moving it halfway down the list can take up to 3-4 seconds for that section of the list to actually show up.
iTunes is just asking for too much hardware. It is pretty odd programming. It shouldn't need this much to run.
Try this: Open up your control+alt+delete system performance meter. Leave it open, and now using either the scroll wheel on your mouse or clicking on the up/down arrow tab of the scroll bar and holding it, start moving the list up or down,
fast. Your CPU will start working,
hard. I got my dual core to perform at 55% while scrolling in album view, about 25% in cover flow. So while it's probably not a HDD issue like I originally thought, it's definitely about your CPU. I can see why my old Celeron D's where getting choked up. I'm not really a pro at CPU's, but if a E6800 is using 55% of it's resources to simply scroll a lst, anything in the performance area of a P4 is going to have serious problems.
Oh yeah, and on a side note, another reason why things were adding so slow was because of the "organize my music" option.
EDIT: So I just tryed that same test on my 2-3 year old eMachines Athlon 3200+, and when just holding the scroll arrow down in album view, it maxed the CPU's abilities. I haven't tried it on my newer (better?) Celeron D 3.20GHz, but I'm guessing it will get similar results.
I'm looking at the system requirements specified by Apple, and it's almost funny. 500Mhz+. My first computer was an original Celeron HP running at 667Mhz ,and iTunes is what put the thing at the curb. After I loaded it, and attempted to run it, it pretty much crashed the system beyond my skills to repair.
