Hello Wonder if you can help me with an issue that is being reported to us via our users.
We use NiFi to transfer evidential phone data across our network and place it on to our networked file storage server. Most files are in excess of 100gb, and we have allocated the server for this work a 10gb NIC. Although we do not expect the transfers to reach these speeds, usually we see transfer speeds of more than 1gbps and files move over pretty quickly. In the last two months, our users have reported to us that it is taking significantly longer for files to reach the destination. Upon looking, the transfer speeds have dropped to roughly 5mbps. I have asked our Network team to look at firewall rules to see if there is a bottleneck on the Network anywhere, but there isn't. we've also migrated the virtual server which NiFi is configured on and changed network switch ports etc to see if this has made any difference, but nothing. To test the network even further, I mapped from the NiFi virtual server to the file storage server and transferred over a large file to test speeds. This moved over at 1.2gbps with no issues at all. The "get file" and "put file" commands have not been touched since they were originally configured, and we are currently using NiFi version 1.5.0. The server is running OS Windows Server 2022. Any help you can provide as to what we can check next to get this working would be very much appreciated. Thanks, Jordan.
