Problem with AMS Edge Servers
Hi,
I've set up VOD streaming solution with 1 origin and 3 edge servers, all on AMS 5.0.1, the problem I have is that I get poor streaming performance.
Once more than 200 users come online the performance imeddiately becomes sluggish, there is a lag in Video seek and buffering.
The problem seems to be in the edge servers. If I take one of the edge out of Load Balancer and access directly (only me, no other users accessing it) everything is fine and quick. Also if I restart the Edge for 2-3 hours it work ok. (CPU load is only 1% when the sluggish performance begins and it never goes up).
I've modified following lines in my config from default values:
in fms.ini I've set:
SERVER.FLVCACHE_MAXSIZE=10240
in Application.xml I've set:
| <Process> |
<Scope></Scope>
<Distribute numprocs="3">inst</Distribute>
<LifeTime>
<RollOver></RollOver>
<MaxCores></MaxCores>
</LifeTime>
| <MaxFailures>2</MaxFailures> | ||
| <RecoveryTime>0</RecoveryTime> | ||
| </Process> |
in vhost.xml I've set:
| <CacheDir enabled="true" useAppName="true"> | |||
| <Path>/home/fmsdvrcache</Path> | |||
| <MaxSize>32</MaxSize> | |||
| </CacheDir> |
Hardware specs for edge servers are:
Core i7-3550 3.7GHZ
16GB RAM
80GB Intel 320 series SSD
I tried many different configurations but nothing helps. Can anyone suggest anything?
