Hello.

We are using Kurento media server, which is built on top of Gstreamer.

Webrtc-webrtc.

We are testing about 6-7 viewers with a single master with one to many scenario
and getting the following output on processor with top, can you please help us
understand what is this fork queue doing while the fork rtp-session is running
only 0.3% of cpu each and queue is running 5% of cpu each?

Server specs: 

Server: Dual E5-2620 v3 (6 Cores, 2.40 GHz)
Second Processor: E5-2620 v3 (6 Cores, 2.40 GHz)
Os: Ubuntu Linux 14.04 LTS Trusty Tahr (64 bit)
Ram: 32 GB RAM

Is it gstreamer's queue element?
Is there a way to decrease cpu usage?
