[Icecast] How analyze performance (buffering) problems ?

[Andrew V. Kuzik]

Hi!


        <clients>200</clients>
        <sources>50</sources>
        <threadpool>40</threadpool>
        <queue-size>40524288</queue-size>
        <client-timeout>50</client-timeout>
        <header-timeout>30</header-timeout>
        <source-timeout>30</source-timeout>

Try to increase queue-size - that should help to serve buffering problems.

EP> I've tryed to load one of our relay with the shell scripts used on
EP> http://icecast.org/loadtest1.php.
EP> Settings was :
EP> # max concurrent curls to kick off
EP> max=100
EP> # how long to stay connected (in seconds)
EP> duration=99999999
EP> # how long to sleep between each curl, can be decimal  0.5
EP> delay=100
EP> Here is our mountpoint definition on the tested relay :
EP>  <limits>
EP>        <clients>100</clients>
EP>        <sources>4</sources>
EP>        <threadpool>20</threadpool>
EP>        <queue-size>512000</queue-size>
EP>        <client-timeout>10</client-timeout>
EP>        <header-timeout>10</header-timeout>
EP>        <source-timeout>60</source-timeout>
EP>    </limits>
EP> <relay>
EP>        <server>xxxxxxxx</server>
EP>        <port>yyyyyyyyy</port>
EP>        <mount>/letsgozik</mount>
EP>        <local-mount>/letsgozik-HiQ</local-mount>
EP>    </relay>
EP> We are using icecast 2.3.0 under Debian/GNU Linux (kernel 2.4.24-grsec) on a
EP> AMD Athlon(tm) XP 2000+ with 512 Mo of memory.
EP> Any idea ?
EP>
