Hi,
Maybe a simple method for detecting "slow" elements is to write a
simple print_time element
...
StringAccum sa;
Timestamp now = Timestamp::now();
sa << _string_argument;
sa << " ( " << now.sec() << " / " << now.usec() << " ) ";
click_chatter ("%s",sa.c_str());
return p;
...
And use it in your script, between the elemets of interest.
I think that avoiding packet clone - elements in your script will help.
Anyway, data packet reception (firmware - drivers -click) and packet
sending paths introduces latency too.
