TT vs CQG data feed coalescing

I am in process of moving to X Trader.

I just read on Ninja forum that TT brokers set coalescing of datafeed to 100 ms by default...

Is there any information available on what coalescing used by what broker?

Also - do CQG servers have coalescing and if yes then how big is it?

I know that IB does it by 200ms - but maybe you know that already
depends how high frequency you are. if trading the 5min chart upwards its not relevant...
