Hi all...
I just need some info/tips on how to make icecast perform better;-
I read up on the comparison between icecast and shoutcast Re memory and Cpu but i seem to be getting some major problems.
I had a peak of 58 listeners to my icecast server but was constantly stuttering with 100% cpu utilization.
I stopped the icecast server and then used shoutcast... the users began to connect to the server again.
Shoutcast with roughly the same amount of users uses aroung 40% cpu.
The stream is a 128K mp3 running from SAM.
Server is on 100mbit connection and source is on 2mbit connection (up/down) so i know the source isnt the problem.
Server is only a celeron 2.4ghz with 1gb ram and cant be upgraded unfortunatly so im stuck with this crap server on a great line 
My question is, what options do i have that could lower the CPU load when using Icecast?
Apart from changing the bitstream what about settings such as
client limit, threadpool, queue-size etc ...
PS, Im using 2.3.1 on Win2003.
Cheers.
| Code: |
<limits>
<clients>200</clients>
<sources>6</sources>
<threadpool>5</threadpool>
<queue-size>524288</queue-size>
<client-timeout>30</client-timeout>
<header-timeout>15</header-timeout>
<source-timeout>10</source-timeout>
<burst-size>65535</burst-size>
</limits> |
Edit: Iv'e changed the threadpool to 20 now, so i will see how that goes...

CPU usage should not be anywhere near 100% especially for the likes of 60 stream listeners. Any usual entries appearing in the logs?

Hi karl,
thanks for your reply, really appreciate it.
the logs more or less empty and theres nothing obvious thats causes the major cpu load... its really getting on my nerves now as i cant reliably stream. the server is from 1and1 and we only got it less than 2 weeks ago, everything else seems to be fine on it thought so it would be a bit difficult to explain the problem to 1and1.
ive attached an image that i took showing the problem, theres only 8 connected to the server aswel! 
if you would like remote access to the server then i am more than happy to give it to you.
regards,
Rico

i have a P4-2.8Gigz machine with 1Gig of RAM dual intel pro 100 NIC and links and 70+ listeners (128k mp3 stream), cpu load is not exceed 45%
may be it's not icecast-related prob? may be some other soft wasting you cpu power? |

Yup,
it wasnt icecast after all.
another server had many connections and was using less than 5% CPU...
i am waiting on our Webhost dealing with the matter, they will not swap the server as of yet as they want to "check it out themselves".

Well the problem got solved by re-installing the server and now icecast 2.3.1_trunkB works lovely 
using 8% cpu with 80+ listeners. perfect!
1.3GB transfered in 15 mins! thank god for free bandwidth!  |
