XBMC on AppleTV taking a while to load iso

[ZuN1]

I have a media server on a gigbit ethernet network and I have XBMC installed on an xbox and an appleTV (ver 9.04.1) both hard wired to the gigabit switch,
When i select a movie (iso) on the xbox xbmc it starts up within 5 seconds pretty much instaneous, now when im on my appleTV XBMC it takes about a minute to load up, anybody know of a way of speeding this up to work like the Xbox version?

Thanks
Rafael

PS the AppleTV os is on the latest verion.

Just to let you know, this is how things work for me as well. My windows-based box that accesses via SMB seems to load up in a jiffy, whereas the ATV can take up to 45 seconds. I always just chalked this up to the slower processor on the ATV taking longer to cache things.

[ZuN1]

Yeah hopefully a Dev or someone that knows what may be wrong can chime in on this.

[aedile]

Well, there might not be anything "wrong" per se. One of the realities of using the ATV is that it's never going to be as fast as a dedicated PC. It's entirely possible we are just running into the limits of the hardware.

[ZuN1]

Well its actually running on an XBOX and I believe the ATV has a snappier CPU

[Winkie]

I can also attest to the fact that it takes a while with only isos and img files on the appleTV, but bigger MKVs and AVI's work almost immediately.

[ZuN1]

Well at least we can narrow it down to ISO's having the issue, and hopefully the Dev's will find that useful.

I've been running XBMC on an Xbox for years and recently got an Apple TV. I use the XBOX for iso movies primarily. My Apple TV takes WAY longer to load an iso movie than my XBOX. XBOX is almost instantaneous. I will post a debug log when I get a chance.

I can also attest to the fact that it takes a while with only isos and img files on the appleTV, but bigger MKVs and AVI's work almost immediately.

For me, the slowness is not limited to ISO and IMG, but also includes the ripped video_ts folder launched from the .ifo file.

[babaraccas]

I've tried loading .iso's from my NAS using three different skins (PM3_HD, Mediastream, Aeon) all having similar results. The first time the .iso movie loads can take minutes, but subsequent loadings are almost instantaneous. In the log file below you will see I loaded "The Bourne Ultimatum" for the first time and it took a few minutes to load up the DVD menu. Then I opened up an .iso called "Pocoyo" which I had previously played, and it opened right away. Then I went back and opened up "The Bourne Ultimatum" again which also opened up right away. The speedier loads also work after reboots of XBMC so it seems to my uneducated self that information is being cached and accessed quicker the second time around. Hope this helps solve the problem. Thanks for all the good stuff!!

My experience when accessing files wirelessly using SMB shares.... (I generally have XBMC nightly SVN updates running on ATV 2.4)

Folders (VIDEO_TS structures) seem to take longer than ISOs (more files to open across the SMB connection).

ISOs with DVD menus included take much longer than ISOs where I have ripped just the movie. ISOs with menus take ages (could be more than a minute for relatively simple menus, longer for complex ones). ISOs without menus generally start playing in 10-15 seconds. Those that have recently been played will restart very quickly, presumably due to local caching of data.

Since almost of of my DVD rips do not have menus I am happy with the current performance of the software. It could always be faster, but I am not in that much of a hurry. :;):

[babaraccas]

Any word on this one? Still a problem and ISO's take minutes to load up? I posted a debug log. Is there any other information I can contribute to the cause? Thanks again for XBMC's awesomeness in all respects!

Any update on this... I see this exactly on the mac mini and the ATV.....

I built an ION system last week and the same issue on the ION.

I dont see it on the XBOX or windows... I wonder if the problem is due to I/O performance on the client creating some cache directory....

on my testing video_ts folders instead of ISO's happens much faster. Its only the .iso's that are slow.

I have tried this on 3 different file server OS's and platforms... same exact issue...

The funny thing in that on xbox ISO's are really fast and VIDEO_TS folders take about 8 seconds to load but its nothing compared the 15-second to a minute I see on the mac. and the 15-20 seconds on ION.

There is a real issue here. I wish the dev's or someone would at least offer a suggestion. Another friend of mine started another thread on the subject and no response there... I will gladly post additional logs and do what ever to solve this one... Its causing a lot of pain for me at the moment with the new platforms....

I actually have this problem on my Macbook!

It can take upwards of 30 seconds to load an ISO over the network for me. Yet it loads normal .mkvs and such, even if they're abnormally large, just fine (which leads me to rule out network speed).

[rufrothy]

I'll post all the details this weekend but the OP posted logs etc but still no comments....
