[Click] safe vs srcr

I changed the static bitrate of safe (1Mbps) to 5.5Mbps and also 11 Mbps,
using SetTxRate(RATE 22), but still it shows the ping latency to be 3 ms.

I tried to find the udp data rate between the two nodes,
With srcr it came out to be 6.88 Mbps
and with safe it was 1 Mbps.

This is wierd, very wierd?
It appears that SetTxRate is not changing the bitrate at all.
I have spend a lot time to solve this problem, any help would be 
appreciated.

thanks,
