OM stress testing
Hello all!
Today we have started stress testing of Openmeetings to detect
reliability and collect statistics.
We plan to run stress tests weekly (on Tuesdays) and send reports to
dev@openmeetings.apache.org .
Tested server configuration is:
OS: Ubuntu 10.04.3 LTS
. RAM 2 GB
. CPU Intel(R) Celeron (R) E3300 @ 2.50GHz
Tested scenario is:
. Start OM conference
. Start recording
. Start screen sharing
. Connect to conference while server is not crashed.
Today results meet our expectations, please see a report below.
Maximum number of the users in the system -- 20
Maximum number of the users in one room of the type "Conference" with
the screen sharing and recordings turned on -- 19.
All the users were logged from two Windows workstations.
Result: After 19 connections server is down.
Error message in log file is: "2013-02-12 08:02:07,844 [NioProcessor-7]
WARN o.r.s.net.rtmp.RTMPMinaIoHandler - Exception caught Java heap space"
Log file is attached.
Thanks,
Vasiliy

It could only happen for example that some other functionality throws this
error.
For example if a file is loaded (accidently) completely in the cache. That
looks like a "performance" issue then but is a bug in the implementation
then cause it will throw the same "heap space issue".
It would be good if you post the complete jvm.stdout log to see the context
of the Heap space error better.
Thanks!

Thanks for the feedback,
could you start to boot the server with -Xms1024M -Xmx1024M ?
Cause I doubt that the Heap space error will happen with 17 or 20 (or 100
users) when 1GB of Ram is really available.

Thanks for the feedback,
could you start to boot the server with -Xms1024M -Xmx1024M ?
Cause I doubt that the Heap space error will happen with 17 or 20 (or 100
users) when 1GB of Ram is really available.

Hi Sebastian,
Just two additional comments from my side:
1. "-Xms512M -Xmx1024M" java keys were used for OM starting
2. All the 19 users in the room had their video windows opened
Previously, when we run OM without "-Xmx" option specified, it died on the
14th user in the room approximately under the similar conditions.

Irina.

What script did you use to startup the server?
You should use the red5-highperf.sh and have a look at the values for Xmx
(max memory) and Xms (min memory).
Please include those runtime informations / configurations from your start
script in the stress test report.
I tried to summarize some links and documentation about performance tuning
once:
http://openmeetings.apache.org/JVMPerformanceTuning.html
Se for example the link to the JVM settings:
http://www.oracle.com/technetwork/java/javase/tech/vmoptions-jsp-140102.html
#PerformanceTuning
But Xmx and Xms is really the most important thing. There is also some param
regard Heap and Thread, that are quite important for performance.
I think by default the JVM will aquire 60 MB.

At a guess I'd say you need more then 2 gig of RAM based on the exception
from the java heap space.

Subject: OM stress testing
Hello all!
Today we have started stress testing of Openmeetings to detect reliability
and collect statistics.
We plan to run stress tests weekly (on Tuesdays) and send reports to
dev@openmeetings.apache.org .
Tested server configuration is:
OS: Ubuntu 10.04.3 LTS
. RAM 2 GB
. CPU Intel(R) Celeron (R) E3300 @ 2.50GHz
Tested scenario is:
. Start OM conference
. Start recording
. Start screen sharing
. Connect to conference while server is not crashed.
Today results meet our expectations, please see a report below.
Maximum number of the users in the system - 20
Maximum number of the users in one room of the type "Conference" with the
screen sharing and recordings turned on - 19.
All the users were logged from two Windows workstations.
Result: After 19 connections server is down.
Error message in log file is: "2013-02-12 08:02:07,844 [NioProcessor-7] WARN
o.r.s.net.rtmp.RTMPMinaIoHandler - Exception caught Java heap space"
Log file is attached.
Thanks,
Vasiliy

RE: OM stress testing

Hi Sebastian,
Just two additional comments from my side:
1. "-Xms512M -Xmx1024M" java keys were used for OM starting
2. All the 19 users in the room had their video windows opened
Previously, when we run OM without "-Xmx" option specified, it died on the
14th user in the room approximately under the similar conditions.
Regards,
Irina.

What script did you use to startup the server?
You should use the red5-highperf.sh and have a look at the values for Xmx
(max memory) and Xms (min memory).
Please include those runtime informations / configurations from your start
script in the stress test report.
I tried to summarize some links and documentation about performance tuning
once:
http://openmeetings.apache.org/JVMPerformanceTuning.html
Se for example the link to the JVM settings:
http://www.oracle.com/technetwork/java/javase/tech/vmoptions-jsp-140102.html
#PerformanceTuning
But Xmx and Xms is really the most important thing. There is also some param
regard Heap and Thread, that are quite important for performance.
I think by default the JVM will aquire 60 MB.
