Long delays before PSH, ACK

retag add tags

Hello,

I am dealing with intermittent slow response issue with APP & DB server.

In the captures, for some TCP streams I observe TCP Delta times of as high as 50 to 100 seconds!!! between previous ACK packet from APP to DB and next PSH, ACK packet between APP to DB. There are no TCP retransmits, TCP DUP acks etc seen on the capture. And adjacent TCP streams around same time between same APP & DB servers work perfectly fine. However, the response times between these two goes intermittently high to 50 msec (normal is 1-2 msec)

Does it mean that APP server is taking too long In preparation to send packet to DB causing the intermittent delays? And we can rule out network issues here?

Thanks,
