Low FPS with rtpgstpay and udpsink

Hi list,

I'm using gstreamer-1.5.90 on ubuntu 14.04.

I want to stream a raw-GRAY8(1088X1000) video over the network.

The two PCs are connected directly (no routers, no switches) with a Fast
Ethernet (RG45) wired connection.

Here's the streaming pipeLine :

gst-launch-1.0 videotestsrc pattern=ball ! video/x-raw, format=GRAY8,
width=1088, height=1000, framerate=40/1 ! rtpgstpay mtu=65000 ! queue !
udpsink host=Recipient_ip_Address port=5000

Here's the recipient PipeLine :

gst-launch-1.0 udpsrc port=5000 caps="application/x-rtp,
media=(string)application, clock-rate=(int)90000,
payload=(int)96" ! rtpgstdepay ! fpsdisplaysink sync=false -v

The problem is the low *fps* that I am having in the reception PC. (I
should have a 40 fps but I am barely having 16 fps)

Can anyone tell me what I am doing wrong here.

Thank you.

Best Regards,
