Jave issue

[Max]

-Xmx8g

for maximum heap memory pool value and

-Xms8g

for initial memory allocation

I change wcs-core.properties value as below: but only 48 stream at the same time now then use server cup avg 53%, How can I have best perfomance than now?
### SERVER OPTIONS ###

Good day.
Please check an output of top command

top

String with "java" shows how CPU is loaded by WCS. Note that you have 8 CPU cores, so 100% in top means that only one core is fully loaded.
Also, your server log is full of messages

Codec not found; pt - 119; current pt - 95

This may affect server performance with writing on server disk. To prevent this you should create the file WCS_HOME/conf/rtmp_agent.sdp with the following content:

v=0
o=- 1988962254 1988962254 IN IP4 0.0.0.0
c=IN IP4 0.0.0.0
t=0 0

a=recvonly

then restart WCS.

Hello, Sir :
Is web call server support flink Cluster?

 

[Max]

Good day.
WCS does not support Apache Flink. This product is for distribute computing, not for media streaming case.
You can use streaming video CDN functions to distribute server load.
