Tennis in-play delay

[megabreak]

Why does Betfair delay bets on Tennis markets when in-play? This can take upto 8 seconds.
Snooker also, possibly other sports.
This is not the case on Horseracing markets.
Once horseracing goes in-play your bets will fire into the market instantly.

Is there any way of improving this delay?

Thanks

I think its because in horse racing the odds move very fast so its a lot more faster market than tennis.

but maybe i am wrong...

I'm pretty sure that Horse Racing in running have a 1sec delay.
