Severe Delay with SendDataMessage Calls

I've been noticing some extremely long delays (2 minutes between send/receive) when calling any of the SendDataMessage functions between two connected Xbox One clients possibly due to something going on inside our networking mesh that I'm currently trying to narrow down. This won't always happen as when I try sending some test messages like the "Hello (data message)" in the sample, it tends to be instantaneous, but will occasionally also suffer from this delay. Is there any reason why this might be happening or any leads to look into?

Found out that we were accidentally writing a massive buffer (16MB) for each message being sent which was causing the delay, and since we were using Guaranteed as out delivery option for these TCP calls, that was giving the illusion of the "Hello (data message)" taking just as long occasionally.
