Multi-cast UDP message throttling

    I'm a software developer and our applications use multi-cast udp messaging between apps. The apps are all executing in the same Windows 10 VM. In a recent update, sorry I didn't note the version number, I get strange behavior. Some message go through fine, but others seem like they are delayed 10 to 20 seconds. For example, I send a message from app 1 to app 2. I note when the message is sent in app 1 and it isn't received in app 2 for 10 to 20 seconds. But other messages on the same socket seem fine. The only theory I could come up with is the size of the packets is the issue. The really small packets seem to throttle while the larger ones are fine (all are within a single frame). Maybe the system is protecting against a denial of service attack by throttling the small packets? Any help would be appreciated.
