SMB share performance degraded

Posted on January 6, 2009 under xn--omr06vg8k1ys.com edit

  • i tried the 04-01-02 build with the new smb code. it took more than 20 seconds to display a 1.2 mbytes jpeg in slide show. (it was around 7 - 8 seconds with previous load). with the new implementation, it took more than 30 seconds to start a divx movie (30 mbytes size). the movie play is very choppy. apprentely, there is some more work required to tune up the new smb client.

    cheers,


  • does that fix solve your performance issues?

    this new smb code seems to work for the majority of people who had issues before. on top of that, the performance seems to be way better. but of course, there are the select few where the performance is not as good in which the mentionned fix solved the problem.

  • i agree, it seems very fast. but, xbmc did freeze while i was navigating some mp3 folders using the new smb implementation. it's only happened once so far so i'm not going to blame smb just yet, but it's never happened to me when using relax.


  • also had the hanging problem. when playing an mp3 then navigating to a folder with lots of sub-folders the song either stops and restarts or xbmc crashes.
    i have the same problem, but i think i'll add to what other users have been saying.

    a) i've queued up a folder (~10 songs) by hitting the y button on a folder.

    b) i start to navigate folders

    c) empty folders do not cause it to "hang"

    d) if i open a folder with sub folders, i get the hang. what it does is that it pauses for 5-10 seconds, and then when it comes back, it skips to the next song in the playlist from the folder i queued up.

    i can recreate this error every time with the january 2nd build. setup playlist, play song, navigate, hit a folder with subfolders, pause, displays folder and skips to the next song.

    hope that helps :)


  • maybe some of you can fix their issues with this info.

    i wasn't having this problem before the 1-2-2004 release, and in fact xbmp works fine :)


  • must be something with your network. this new version is lightning fast on my network. i love it! :lol:

    big thank you to darkie for the port.

    oh i use win2k btw.


  • xbmc-er - how do you change the cache for audio files to 768k?

    (i have very choppy mp3 playback - have a wireless g network).


  • i had this same problem with the old smb code as well. mp3's would restart if you navigated around a bit but it didnt happen consistently.


  • try to change the cache for audio files to 768k. it worked for me.

  • i agree.. the new build is very fast compared to any previous build, and that includes when using smb, relax, ccxstream.

    new smb client code is great.

  • i agree the new version is better but still occasional choppyness when playing mp3s.

    i don't have this problem with xbmp - i think because of the individual cache settings. is this going to be implemented on xbmc?


  • you will get bettere preformace when playing movie media from smb shares on windows servers if you change to "maximize data thoughput for network applications" in "file and printer sharing for microsoft networks"

    thanks,

    no, it didn't fix the problem. whenever there's any activity (browsing to another directory, viewing playlist, etc) other than straight streaming the music it gets choppy as hell. the latest release (the 15th or whatever) is better, but it's still unusable to listen to music to.


  • with the new smb code, xbmc consistently hangs when i am playing a song and navigating folders at the same time.

    the steps i perform:

    1. navigate into smb share
    2. navigate into subfolder
    3. add song to playlist
    4. navigate back to the parent folder
    5. navigate in and out of a few subfolders, until it hangs. usually takes about 4 tries.

    the new implementation does seem to be quite fast though.


  • i can only agree. it's great! i'd say it's about 75% faster in starting a movie. thanks alot. for me this has been the greatest issue with xbmc so far. and the new osd stuff in full screen video... what a treat =)

    ps
    (i'm close to finishing my own skin; retro now... hope to release it within a couple of days)

  • that's what i meant. anyway i'll probably spend some time implementing this feature soon.

  • nations favourate,

    you are building my part up, i'm a bofh not a developer/coder! reading this and other threads on cache/samba mods i think its in some plans...i hope. xbmc is nearing quality for a donation !


  • ???
    it happens the same thing to me. i have the x connected wireless-y. at some point the router goes crazy and i had to reset it to have the network working back. i'll try xbmp with smb.


  • with the new smb code, xbmc consistently hangs when i am playing a song and navigating folders at the same time.
    that's the exact problem i had. i was listening to an mp3 over smb while navigating some folders and then xbmc froze.

    gotta add that i was a doubter that this would fix the terrible mp3 stuttering, but hey....it did *http://www.xboxmediaplayer.de/forums/non-cgi/emoticons/wink.gif

    not perfect, still some pauses occasionally, especially when monkeying up/down the menus. hopefully cache setting will solve this. as for general smb networking speed when pulling directories and video files at startup its blindingly fast. good work!

    q. is there a feature to stream multiple boxes simoultaneously from the one smb directory and have the playback syncd ? usefuly for multiple box installation throughout a house with the option of syncing all streams to the same time delivery of a music file (whole house audio). ok i know you can crank up the amp's volume, but why take the easy route....?!

    regards

  • jayell - will this fix be in the next release then?


  • i am also seeing terrible, yes terrible not poor, smb performance with xbmc-2004-01-15. movie playback is un-useable as well as mp3 playback over smb shares.

    i noticed one comment in this thread suggesting it was the users network, well my network is working fine with xbmp and i can stream between computers over these same shares just fine as well so it is a bug in xbmc.

    network description:
    my xbox is connected over a dlink-dwl2000ap wireless 802.11g client to a dlink-di-624 802.11g router.

    i also found when playing a shoutcast stream and playing a slideshow from a smb share the xbox will eventually hang and when it does it totally hangs my wireless network as well and i have to reboot the router. what could hang the wireless network???

    is the original poster running wired or wireless? what about the rest who say everything is working fine?

    i would suspect there is a bug in the way the smb client is configured in xbmc such as assumptions about mtu or other network configuration parameters.


  • xbmc-er - how do you change the cache for audio files to 768k?
    there's no such function (yet), currentlly the cache level is hard coded in the source code, so users can't change it themselves

  • ok, i'll have a look at it to see if it is the new samba code or the new mymusic
