Here is my situation. I have 2 servers that are running 4 Intel Adapters Teamed for 802.3ad Link Aggregation (4Gbps). I am able to get about 60% utilization when copying multiple files to multiple servers. I do understand the 1GBps max when copying to a single server, that is not the issue here. I have found, that when I am copying multiple folders to a single server, across this Team, I find that the network utilization falls to below 1%, almost .5% total. Total Bandwidth is around 2Mbps, which is lousy. Is this a limitation of the algorythm of the teaming software? Am I overloading the driver\NIC processor? The total data for a single copy, is 3.4GB, 2400 files and 173 folders. Large but not that large. If I use windows copy and transfer this folder, using two seperate file copies, I get 15% Utilization. This is good, since it is using a single NIC. If I add 1 more copy of this folder, for 3 total, it tanks and ends up utilizing the above .5%. The data just stops going on the wire. This is localized between two sending servers. I can copy this same folder, 6 times to 3 servers without issue. Can someone help me with locating the bottleneck?
