With default window size of 64KB, and a delay of 75 msec, you should only get around 7Mbps of throughput with TCP.
You would need a window size of about 1MB in order to fill up the 100 Mbps link.
1/0.75 = 13.333 (how many RTTs in a second) 13.333 * 65535 * 8 = 6,990,225.24 (about 7Mbps)
You would need to increase the window to 1,048,560 KB, in order to get around 100Mbps.
13.333 * 1,048,560 * 8 = 111,843,603.84 (about 100 Mbps)
I realized I made a typo: 1/*0.075* = 13.333 not 1/0.75 = 13.333
