udpsrc performance

[parag.salasakar]

Hi

I am trying to decode MPEG2TS bistream with following pipeline

gst-launch -v udpsrc port=5004 caps="application/x-rtp, clock-rate=90000,
media=(string)video" ! gstrtpjitterbuffer ! queue ! rtpmp2tdepay !
mpegtsdemux ! queue ! ffdec_mpegvideo ! videoscale ! ffmpegcolorspace !
autovideosink on my DSP  platform

However i noticed that when I try 

gst-launch -v udpsrc port=5004 caps="application/x-rtp, clock-rate=90000,
media=(string)video" ! fakesink silent=1 

CPU utilization goes to 35% to 40% for 4 Mbps streams, which sounds weired
to me (how can just udpsrc take 35% of CPU?) 
AM I missing anything?
