Anyone else have problems with RIthmic?

Hey guys. I used Zenfire for years before the whole debacle back in December. I then switched to Rithmic after having problems with CQG.

I've noticed that during open bell when I submit the orders, there is quite a bit lag. Sometimes it's around 1000 ms! This can potentially mean 2-3 ticks of slippage. I'm just wondering if it's something on my end or has anyone else experienced this as well? I have AMP has my broker and using Ninjatrader as my platform.
