Increased time placing trade when live,

When placing a trade on MT4 demo, a trade takes approximately 2 - 4 secs to place, how much longer am I looking at on a live account?

I currently trade live with Mt4 (broker IBFX) and have no latency issues. I place a trade and it’s as fast as the demo. Haven’t noticed any issues placing a trade. In a faster moving market (news releases etc.) I have noticed a requote but thats not so much an inconvenience but rather a fact of trading I find.

I have not noticed any time difference when placing a trade on my live account than there was with my demo account either.
I am trading a live MT4 account with LiteForex.

Same as has been said, I’ve never noticed any significant time delay difference between demo and real and I use both types regularly
