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. |

sendfile should be enabled along with AIO.
Maybe you are using PHP script to streaming files, it is low efficient, if so, you should consider using internal redirect feature.

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!
