OK I ran png gauntlet on blacks aeon cut the media folder from 113 mb to 100mb.
But I could not see a difference on the debug info freemem/cpu. But I am wondering why does it need to run 59,8 FPS and 96% on the CPU. It is just standing there doing nothing - What it had to present on the screen was there....so I would have expected it to go down in FPS and CPU after a screen load?!?

For those who are suffering with lag or slowness in Aeon could you state you system layout. Even though one skin might run ok and another not, does not mean the slower skin is crippling the machine. It could mean the slower skin has just pushed the machine over the edge whereas the other skin could be just under that limit.
Personally I would say the extra gfx and display is affecting things. I am not sure how the gfx engine works on XBMC where it comes to alpha blending but there is more in aeon that would be blended over other skins. Take the cd/dvd cases for example these have alpha channels and will be alpha blended whereas the background fanart does not need alpha blending.
One thing non of you have mentioned is how your images are stored. This would make a difference on a system if for example you have all your menu fanart stored on a slow drive and it was pushed over the network to get to xbmc...
- Are you using slow hd's or solid state. SSD's remove need for defragging.
- Are you pushing your images over a 10mb, 100mb or 1gb network.
- if pushing over network are they coming from a slow hd on that networked machine.
- do you have disk indexing on or compression on on the machine where the images are stored.
This kind of information could also help to find out where your bottlenecks are.
My recomendations for speed.
Always strip drives. If you have storage of more than one drive you can get better read speeds by striping those 2 drives... about 60% of the original speed from my experience.
If you are about to replace your media rig drive consider a solid state. I am running 4 ssd's raid 0 @ 800mbs on my media rig and its blinding. With Tiny XP installed I can switch the machine on and once past bios posting I can boot into xbmc in just under 2 seconds.
Also ssd's will help with loading lots of skin images into memory and any caching for posters etc.
Always make sure your network is running at full capacity. If you have gb nics for example make sure they are pushing 1gb and not handshacking at 100mbs. You can check this 2 ways.
- If your router has lcd indicators to show 1 colour as 100mbs and anotehr to show 1gb.
- Go into your network settings. Select the nic configuration and check what speed is set. Check for half duplex or full duplex.
Basically make sure you are pushing the network to the limit.

@MrTourettes: So can u confirm that AEON runs smoother with SSD?
It's, I am building a HTPC right now, and thinking of buying a SSD for the OS and XBMC only.
I know the OS boots much faster and the programs as well, but I don´t reebot so much so only for that would be to expensive ;-)
If the SSD does not help to run AEON better I am thinking of buying a small 2,5" for the OS to save money.

The rest will be Zotac ION 330. And I am thinking of buying the new OCZ Agility. (not the fastest, but for 100€ I think will help to improve overall performance.
Will not buy 2 for the OS. Beacause for the OS I only need 10GB (20GB if Win and Linux)
And SSD is not only for read and write time,a lot for response-time and this will not get better with raid.

I don't think you'll find any difference from the compression on the skin's PNG files. Remember that all PNGs have to be decompressed to WxHx4 before sending them to the GPU and the GPU will often allocate a larger amount of memory to hold them, for the purpose of alignment and such.
Also having tons of small textures is generally a bad thing for performance, both on the GPU and the loader. You have to open a file (the seek to + open = probably longer than the read), read, decompress into memory, gentexture, upload to GPU. Now when you go to use it, you're thrashing the GPU cache because you keep swapping out textures. Does XBMC support texture sheets, where you load one image that has a bunch of your details on it, then you carve it up by UV coodrinates for each control? That could help too.

Well my spec with a SSD disk still gives me no smooth aeon experience.
CapnBry is onto something - the amount of textures in aeon is huge compared to other skins. All the texture swapping probably causes aeon to take a performance hit.
Im currently investigating some animation stuff also.

I just enabled the Debug logging and played around with all the views a bit.
In Multiplex view my FPS never drops below 30 no matter what I do. CPU load goes up till 75% if I scroll through Movie Multiplex view as fast as possible. When doing nothing the CPU load used by XBMC is around 20%.
In Showcase my FPS is around 20, sometimes even lower. CPU load is about the same as in Multiplex view.
In List view FPS is around 30 when doing nothing, fast scrolling brings it down to 20.
Wall view is the worst. Idle FPS is around 20, fast scrolling between 10 and 15. CPU load goes up to 85%.
I use Black's mod and have Backdrops and Fanart on, all fanart 1920x1080, posters 1000x1500, MediaFlagging and DVD cases on as well so probably the most you can get from Aeon.
EDIT: Ok this is strange/funny: I turned off fanart and backdrops and the performance in Multiplex got a lot worse ?!?!
