Lightwaverf commands delay

I am seeing a lot of delay in the lightwaverf commands execution, each command takes almost 2-3 seconds after the previous is executed this creates a lot of delay in my rules when i try to exeute a scene (multiple lights on or off). I have seen the parameter in binding configuration which states delay in command and adjusted this to 300 (ms i assume) still the execute is pretty slow. In fact overall scenes using rules method of when xxxx then sendCommand 1,2,3,4,5,6,7 is very slow takes almost 3-4 seconds to start executing.

any help or pointers ?
