    Thanks NiteWave, i will try AIO when i have owned a license. Maybe, it wouldn't help because the limit of VPS itself. So i am going to add more node.

    You mean when we enable AIO, we must disable "Use sendfile()" to allow AIO starting to work? I have tried 2-CPU trial license, but that time i didn't disable sendfiles option and the result wasn't better.

    After that trial time, i understood that i got big disk I/O problem when other sites was using my media url to stream on their site. And come to now, i feel that it is difficult to access realtime stats page while peak hours so that is very annoy, viewing server logs is difficult too.

    LiteSpeed is a great web server, i hope via my case. LiteSpeed Team can figure something out and optimize it far better.

    I am not sure i am using PHP script to streaming files or not. My scripts create a playlist file (asx format) with full URL to media file. Can you check for it me? http://vn2rap.com/m/#Play,20200 --- http://vn2rap.com/m/asx.php?type=1&id=20200

    I am using PHP. How can i use internal redirect?

    This is the main thing: http://vn2rap.com/m/#Play,20200
    Player streaming asx create by this link: http://vn2rap.com/m/asx.php?type=1&id=20200 it doesn't show directly on browser, you should use some downloader to download. It will show it's content.

    Does it shows that: "cannot display ..." ? You should try to refresh after a coupe seconds. This issues is what i have mentioned. In cases, do you need to access SSH, and litespeed cp to messure my problem?

    looking at the failcnt column, there are a lot of failures.
    please increase barrier/limit, especially tcpsndnif at host first.
    let's see if any improvement.

    I have sent ticket to host, i will reply when barrier/limit and tcpsndnif has been tweaked. You can continue to monitor it as long as you want.

    Thank you so much, NiteWave!

    ... The bottneck is the VPS provider limited my banwidth usage to 4 MB/s (normally my site used 6 MB/s), everything will be drop when it over the limit :(.

    Thanks NiteWave, if you didn't find out that, i wouldn't know the situation. Adding more node for load balancing is my solution now.

    while everything drop, CPU usage of litespeed process up to 100% -- so the reason is the bandwidth limit. this result will benefit other uesrs. Thanks for the feedback. I'd mark this thread "solved".
