Why inplay running bet gets response slow.?

[David Sutcliffe]

Hello
I am using betfair API to play bet. When the race is not in running betting response comes as usual and its fast.But when the race is in running and i place the bet using betfair api, Response comes late compare to when race was not in running. Does the Betfair response server creates problem? Please help me out.
