| - | For this test with RTT of **0.010ms**, we have a transfer period of **16s**, or a throughput of **239Mbps**. Note that there is a BDP of 0.010ms * 1Gbps = **1.31072KB**. We had a Net In average of **450.251Mbps** and Avg: **450.251Mbps**, with Avg disk write of: **225.103Mbps**. | + | We assume GridFTP is installed on both machines in directory "~/gridftp". |
| - | Using the dummynet with a RTT set to **100ms**, we have a transfer period of **20s**, or a throughput of **191.2Mbps**. Note that there is a BDP of 100ms * 1Gbps = **12.8MB**. We had a Net In average of **309.842Mbps** and Avg: **398.217Mbps**, with Avg disk write of: **265.46Mbps**. | + | Create the file and host the GRIDFTP server: |
