Dear expert,
How much throughput I can have on 100mb ethernet ckt. with rate limit of 100mb
Is there any formula?

Mahesh,
It would actually depend on various factors like Application (TCP vs UDP), window size, latency, packet loss etc
Here is a good link on how to calculate the throughput

If you thoughput you're thinking of is data throughput, the maximum throughput would be the ratio between the data payload and all overhead. Or, payload usage divided by the total bandwidth consumption.
For instance, if you were using TCP and sending payload in 1460 segments, there's minimally the 40 bytes of IP and TCP overhead, 18 bytes of Ethernet L2 overhead (assuming no VLAN tag, etc.) and 20 bytes of Ethernet L1 overhead. Or 1400/1538 * 100 Mbps = 91 Mbps. If you were only sending 1 byte of payload per frame, then you would have 1/84 * 100 Mbps = 1.19 Mbps throughtput.

Oops! The first calculation should have been 1460/1538 * 100 = 94.9 Mbps.
