Hi, we running a system with one server and 4 clients. All 4 clients send their data at the same time to a server. Sometimes we have big delay, which is a big problem for our system. To figure out whats happens, we run IPERF on all 4 clients(Linux). The server is an windows system. If all 4 clients sending datas at the same time to the server, we got a very long delay, up to >10sec. But only client has this delay. We can't explan whats going on. On wireshark we can see, that the client sends an PSH ACK an after that we have delays. What could be a reason for that and how can we fix this?

In this case you should disable Delayed ACK at the windows system
